    Appeal from the Judgment Entered November 12, 2015
    In the Court of Common Pleas of Clarion County
    Civil Division at No: 645 CD 2009
    BEFORE: LAZARUS, STABILE, and STRASSBURGER,* JJ.
    OPINION BY STABILE, J.:                                      FILED APRIL 11, 2017
    Appellants, Dennis A. Renninger and his wife, Patsy D. Renninger,
    appeal from the judgment of November 12, 2015. We affirm.
    On May 25, 2007, Appellant Dennis Renninger was at work in the
    Clarion,    Pennsylvania      plant    of      his   employer,   Commodore   Homes
    (“Commodore”), a manufacturer of modular homes, when he sustained a
    serious injury to his foot.       While under construction, each modular home
    moves along an assembly on wheeled casters attached to its underside. Mr.
    Renninger was injured when a caster ran over his foot.              Appellants sued

    Retired Senior Judge assigned to the Superior Court.
    J-A23029-16
    Appellees A&R Machine Shop (“A&R”)1 and Cass Hudson Company (“Cass
    Hudson”) as the designers, manufacturers and suppliers of the casters.
    Appellants alleged causes of action for strict products liability, negligence,
    breach of implied warranty, and loss of consortium causes of action, claiming
    the casters should have included toe guards. The case proceeded to a June
    22-25, 2015 jury trial on Appellants’ strict products liability/design defect
    claim.2     The jury returned a defense verdict, finding Cass Hudson did not
    supply a defective product.         Appellants filed timely post-trial motions on
    June 30, 2015. The trial court denied those motions on November 3, 2015.
    The verdict was reduced to judgment on November 12, 2015, and this timely
    appeal followed.
    Appellant raises seven assertions of error, which we have reordered
    for clarity of analysis:
    I.     Whether in its November 3, 2015 order, the trial court
    erred in denying [Appellants’] motion for post-trial relief
    which requested in the alternative either: (1) an order of
    a judgment notwithstanding the verdict setting aside the
    jury’s verdict and issuing an award for [Appellants], or (2)
    ordering a new trial in this matter, where the issuance of
    such an order was clearly supported by the evidentiary
    record and controlling case law and the denial of such
    ____________________________________________
    1
    Appellants and A&R reached a settlement agreement prior to trial. A&R is
    not participating in this appeal.
    2
    The trial court entered summary judgment in Appellees’ favor on
    Appellants’ manufacturing defect and failure to warn products liability causes
    of action.   Appellants withdrew the negligence and breach of implied
    warranty claims prior to trial.
    -2-
    J-A23029-16
    request deprived [Appellants] of an adequate statutory or
    legal remedy and was clearly contrary to the applicable
    case law.
    II.    Whether in its November 3, 2015 order, the trial court
    erred in finding that it properly allowed evidence and
    testimony of industry standards and employer conduct to
    be considered by the jury.
    III.   Whether the trial court erred in its April 17, 2015 order on
    motions in limine where it expressly stated that the
    Pennsylvania Supreme Court’s ruling in [Tincher3] allowed
    for the introduction of the following at trial:
    (a)    Industry safety standards;
    (b)    OSHA safety standards;
    (c)    Employer conduct; and
    (d)    Conduct of third parties, including but not limited to
    assumption of risk by [Mr. Renninger].
    IV.    Whether in its November 3, 2015 order, the trial court
    erred in finding that it properly instructed the jury on the
    question of defective design of a product. Specifically,
    whether the court erred when it instructed the jury on the
    factors to consider in applying the risk utility analysis
    required pursuant to the Pennsylvania Supreme Court
    decision in [Tincher], when it instructed the jury to
    consider a seven-part test which was not adopted by the
    [Tincher] decision.
    V.     Whether the trial court erred when it failed to properly
    craft a jury verdict question and failed to place such jury
    questions in a sequence that resulted in the jury deciding
    the case before being asked to apply the risk utility
    analysis required by [Tincher].           Specifically, jury
    questions 1 and 2, which were generic questions that did
    not require the application of the risk utility analysis, and
    consequently this case was decided without the application
    of risk utility by the jury.

    -3-
    J-A23029-16
    VI.    Whether in its November 3, 2015 order, the trial court
    erred in finding that it properly disallowed a jury
    instruction on the doctrine of intended use in the context
    of products liability design defect cases pursuant to the
    Pennsylvania Supreme Court decision in [Tincher].
    VII.   Whether the trial court erred in its January 27, 2011 order
    on [Appellees’] motions for summary judgment where it
    misapplied Pa.R.C.P. [No.] 1035.2, in that it relied upon an
    affidavit to prematurely grant summary judgment in favor
    of [Appellees] before the close of discovery and dismissed
    certain counts of [Appellants’] amended complaint; and
    more importantly used that same affidavit to conclude that
    the third party/employer was the designer of the subject
    product, and that neither [Appellee] designed the wheeled
    caster assemblies at issue.
    Appellants’ Brief at 4-6.
    Before we analyze Appellants’ legal arguments, we will review the
    facts introduced at trial.   Mr. Renninger’s job at Commodore was to help
    build and finish roofs. N.T Trial, 6/22/15, at 60. Mr. Renninger’s plant built
    roughly ten to twelve homes at one time. N.T. Trial, 6/23/15, at 21. The
    homes under construction moved around the assembly line on casters bolted
    to their undersides.   
    Id. at 22,
    24. Originally, Commodore positioned the
    casters several feet inside of the home’s outer frame, such that a moving
    caster could not run over the foot of a person standing alongside a moving
    home. 
    Id. at 22-23,
    92, 114-15; N.T. Trial, 6/24/15, at 96. Commodore
    repositioned the casters to the outer edge of the homes to prevent bowing in
    -4-
    J-A23029-16
    the floor joists.4     Id.; N.T. Trial, 6/24/15, at 58.     Commodore modified
    twenty casters to accommodate the new location. R 796-802. Cass Hudson
    and A&R Machine subsequently supplied additional casters fabricated to
    meet the new specifications. 
    Id. The twenty
    modified casters remained in
    use at the time of Mr. Renninger’s accident, and it was not possible to
    distinguish the casters Commodore modified from the unmodified casters
    subsequently supplied by Cass Hudson. 
    Id. Mr. Renninger’s
    accident occurred while he was on the plant floor
    speaking to his foreman.          N.T. Trial, 6/23/15, at 26-28.   Mr. Renninger
    testified that Commodore never trained its employees on Occupational
    Safety and Health Administration (“OSHA”) regulations regarding the plant
    floor.    
    Id. at 85.
       Mr. Renninger was not aware of any OSHA regulation
    requiring the use of steel-toed boots on the plant floor, and he did not own
    steel-toed boots on the date of the accident. 
    Id. at 83-85.
    He was wearing
    tennis shoes when the accident occurred, and he was aware that the casters
    did not have a guard to prevent the wheel from running over a foot. 
    Id. at 80.
    Mr. Renninger also testified that the plant floor was not level, such that
    some of the wheels underneath a moving modular home would touch the
    ground while others did not.         
    Id. at 85-86.
      Mr. Renninger believed a toe
    ____________________________________________
    4
    The record indicates that Commodore switched from mobile to modular
    homes the year before Mr. Renninger’s accident. The interior placement of
    the casters worked for mobile homes but caused bowing in the floors of the
    modular homes.
    -5-
    J-A23029-16
    guard on the caster would have prevented his injury.      
    Id. at 96-97.
      Mr.
    Renninger did not believe a steel-toed boot would have prevented his injury.
    
    Id. at 97.
    Richard Guzicki an employee of Appellee Cass Hudson who helped
    handle the Commodore account, testified that Cass Hudson is a distributor of
    casters and wheels. N.T. Trial, 6/24/15, at 5. Cass Hudson consults with its
    customers to determine an appropriate caster for their needs. 
    Id. at 5,
    17.
    Dale Toney, director of special operations for Commodore, testified that he
    relied on Guzicki to supply an appropriate wheel for the height and weight.
    
    Id. at 80,
    83, 110.        According to Guzicki, Cass Hudson does not advise
    customers on the need for toe guards in a given application, and does not
    analyze the safety needs at a customer’s plant.      
    Id. at 43-45.
      Likewise,
    Cass Hudson personnel did not visit the plant where the accident occurred.
    
    Id. at 47.
    Thus, Cass Hudson had no opportunity to observe the condition
    of the plant floor.5
    Delbert Miller, one of the owners of A&R Machine Shop (“A&R”),
    testified that A&R fabricated the brackets that held the casters to the
    modular homes. N.T. Trial, 6/24/15, at 57. Cass Hudson is one of A&R’s
    ____________________________________________
    5
    We observe that the plant closed shortly after the accident. Cass
    Hudson’s legal team never had an opportunity to examine the plant, the
    floor, or the caster that caused the injury.
    -6-
    J-A23029-16
    largest customers. 
    Id. at 67-68.
    Like Guzicki, Miller never visited the plant
    where the accident occurred. 
    Id. at 69.
    Both parties produced expert witnesses.      Paul Dreyer, a mechanical
    engineer and Appellants’ expert witness, described the roles of Commodore,
    Cass Hudson, and A&R:
    Okay. Commodore is the manufacturer of the modular
    homes, so they know modular homes. A&R Machine is basically
    a machine shop that builds metal fabricated parts, things that
    drill holes and a certain size and shape. They supplied a metal
    fabric part which they called a bracket to Cass Hudson. And
    Cass Hudson took the bracket and mounted it to the caster
    assembly and then supplied it directly to Commodore to be used
    underneath the modular home.
    N.T. Trial, 6/23/15, at 114. Dreyer testified that the casters attached to the
    outer edge of the modular homes were defective because they lacked a toe
    guard. 
    Id. at 117.
    [T]he main reason why a toe guard is important for this
    particular application is because this is a very large wheel with a
    very heavy load. That can be very dangerous. And because of
    that circumstance, it needed to be—the workers needed to be
    protected from the possible movement of that very heavy load
    onto their foot.
    
    Id. at 117-18.
    Further:
    For this particular caster assembly to have, like I
    mentioned, a large wheel which has no guarding, no protection,
    which is—could instill a very serious injury on a worker who is
    paying attention to his job and not thinking that there’s an
    imminent hazard, imminent danger right below him until
    obviously after it occurred. And if this caster had a guard
    assembly, a toe guard assembly, it might have pinched his foot
    but pushed it out of the way so it wouldn’t be ridden completely
    -7-
    J-A23029-16
    over and partially—according to the documents, partially up his
    ankle before they could get it off of his foot and cause that
    serious injury.
    
    Id. at 120.
      In Dreyer’s opinion, the toe guard was preferable to using
    another worker as a spotter, and it was also preferable to using a buzzer or
    beeper on a moving modular home.       
    Id. at 121.
      A spotter may not see
    everything, and a buzzer might not get the attention of a worker wearing ear
    protection. 
    Id. Multiple homes
    moving along the assembly line and beeping
    could cause confusion. 
    Id. Dreyer stated
    that Cass Hudson’s suppliers offer toe guards for sale in
    their catalogues, but he acknowledged that a toe guard for the casters
    Commodore purchased would have needed to be custom designed.          
    Id. at 118.
    A custom designed toe guard would have increased the cost of each
    caster by 10 to 12 percent. 
    Id. at 123-25.
    Dreyer said it should have been
    obvious to Cass Hudson that a toe guard was necessary, once the casters
    were moved to the outer edge of the modular homes. 
    Id. at 206.
    Dreyer believed the use of a toe guard would have been in accord with
    industry standards. “The caster industry has done that analysis and come
    up with a couple of different toe guard designs, and I have my faith in their
    industry that that design minimizes injury.”    
    Id. at 161.
       Commodore’s
    compliance, or lack thereof, with OSHA regulations was not relevant to
    Dreyer’s analysis of the product design. 
    Id. at 201,
    209.

    J-A23029-16
    The defense expert, Gary Hutter, testified that no industry standard
    requires heavy-duty casters to have toe guards. N.T. Trial, 6/24/15, at 167-
    68.
    Q.    Is that a standard that exists in the wheel supply
    industry?
    A.    No, it is not. It’s not a standard in the wheel supply
    industry, nor is it a requirement by OSHA. I’m on an ANSI
    [American National Standards Institute] committee that’s
    involved with casters. I voted on two of their standards. It’s not
    a requirement in those standards either.
    Q.    Do you know of any law, any regulation, any
    standard or any literature that coincides with Mr. Dreyer’s
    opinion that all heavy-duty casters must contain guards?
    A.    No, I’m not aware of anything like that.
    Q.    Have you ever heard any person or any expert offer
    that opinion at any other time than in this case?
    A.    No, I have not.
    Q.    Can you tell us what the standard is with regard to a
    reasonable seller of a caster dolly and wheels such as that we’re
    dealing with here?
    A.     Well, in essence, the caster dolly is a component in a
    product, the product being the—this house that’s being made,
    and it’s a component someone’s buying—
    [At this point, Appellants’ Counsel successfully objected to
    Hutter’s characterization of the caster as a component of the
    modular home]
    Q.   Setting aside components, what is the—what is the
    standard of what a reasonable seller is expected to comply with
    when they are selling a caster dolly as was sold in this particular
    case.
    A.    In essence, that it would be compliant with codes
    and standards, that it would be reasonably safe, that it would
    -9-
    J-A23029-16
    perform the utility as they understood the utility to be, those
    kinds of things.
    Q.    And in this particular case, is it your opinion that
    Cass Hudson complied with the standard—the applicable
    standard that you just indicated or that it did not comply?
    A.     Yes, that it did.[6]
    
    Id. at 169-71.
    Hutter further elaborated on the ANSI standards:
    Now, wheels have been around for a long time; and most
    of the wheels we encounter do not have any kind of wheel
    bearings on them. Now, in some situations, maybe a wheel
    bearing makes sense; but let’s see if the codes and standards
    require wheel bearings. When I went to the ANSI code—and
    ANSI is American National Standards Institute. They have codes
    on casters and wheels. I voted on their standards on those
    issues. They do not require that wheel guard or any wheel
    guard is mandatory on—on this kind of product. You go to the
    codes and standards and you look. Well, what do we need? And
    I’ve said this repeatedly. You have a trained person. You have
    spotters. You—you have safety shoes. You make sure the area
    is clean. In addition, you might use a horn. You might use a
    light. You might use other kinds of communication. You make
    sure that there isn’t going to be a problem because this would be
    like driving a heavy forklift truck and not being able to see
    what’s in front of you.
    
    Id. at 226.
        As we will explain below, Appellants have not developed any
    argument challenging Hutter’s testimony that Appellee’s casters met
    industry and ANSI standards.
    ____________________________________________
    6
    Given this testimony, Appellee’s assertion that it introduced no evidence of
    industry standards is incorrect. See Appellee’s Brief at 11.

    J-A23029-16
    Hutter confirmed that Cass Hudson was not in the fabrication business
    and could not have fabricated a toe guard for Commodore’s casters. 
    Id. at 174.
    It would have been impossible to design an appropriate guard without
    knowing the contours of the floor:
    Well, first of all, there’s been some discussion about the
    undulation of the floor of the building where this is being
    manufactured; and if you have a guard and then try to—I
    believe Mr. Toney […] wanted it to be close to the floor obviously
    so that a toe or foot can’t get underneath there; but because the
    floor goes up and down—which normally a floor would because it
    would have drains in it, because concrete is never made
    perfectly flat, because there are expansion joints and all those
    kinds of things, that if he put it too close to the floor, it would be
    a problem. And it would gouge into the floor. And if he put it,
    obviously, too high, it’s not going to protect too many people
    unless they have a very big shoe on or something like that. So
    you’d have to know that information about the floor.
    
    Id. at 175
    Hutter believed Cass Hudson did not have the information it needed to
    make a safety recommendation, and was not aware that spotters and safety
    shoes were not in use, as its personnel never visited the plant. 
    Id. at 212,
    219.   Hutter also stated that toe guards present their own risk of injury,
    including running over electric cords or hoses.      
    Id. at 182.
    Hutter opined
    that toe guards did not pass his risk-utility analysis because they would not
    necessarily protect a worker’s foot and they pose additional hazards. 
    Id. at 196-97,
    224-25.      Hutter would not have recommended the use of a toe
    guard on the casters in question. 
    Id. at 213.
    Hutter did not believe it was
    certain that a toe guard would have prevented Mr. Renninger’s accident. 
    Id. - 11
    -
    J-A23029-16
    at 191, 196.          Mr. Renninger’s soft tennis shoes could have slipped
    underneath a toe guard, depending on where he stood and the gap between
    the toe guard and the floor at that location. 
    Id. at 196.
    Hutter testified that utility carts used to carry thousands of pounds of
    steel, concrete, or brick generally do not have toe guards on the wheels. 
    Id. at 187.
    Similarly, the industrial carts at retailers such as Home Depot do not
    have toe guards. 
    Id. at 188.
    Hutter claimed the use of a spotter and safety
    shoes are the most successful methods of preventing the injury Mr.
    Renninger sustained.      
    Id. at 192-93,
    201-02.        The toe of a typical safety
    shoe rises two inches above the sole, such that a caster would be unlikely to
    roll over the wearer’s foot. 
    Id. at 208.
    The wheel would bump the safety
    shoe and the wearer would have time to move his foot clear of the wheel’s
    path.    
    Id. at 208-09.
            Persons operating the machine that pushes the
    modular home are required to comply with government safety standards.
    
    Id. at 194.
    In sum, Hutter did not believe Cass Hudson supplied defective
    casters. 
    Id. at 198.
    Hutter believed an unsafe workplace, rather than the
    lack of a toe guard, caused Mr. Renninger’s injury. 
    Id. at 198-99.
    We now turn to Appellants’ legal arguments. Appellants argue the trial
    court    erred   in   denying    their   motion   for   a   new   trial   or   judgment
    notwithstanding the verdict (“JNOV”). “Our standard of review regarding a
    trial court’s denial of a motion for a new trial is limited. The power to grant
    a new trial lies inherently with the trial court and we will not reverse its
    - 12 -
    J-A23029-16
    decision absent a clear abuse of discretion or an error of law which controls
    the outcome of the case.”     Kaplan v. O'Kane, 
    835 A.2d 735
    , 737 (Pa.
    Super. 2003) (quoting Siegal v. Stefanyszyn, M.D., 
    718 A.2d 1274
    , 1275
    (Pa. Super. 1998)).   The following governs our review of the trial court’s
    denial of JNOV:
    JNOV is the proper remedy in a civil case where the
    evidence presented at trial was insufficient to sustain the verdict.
    Nonetheless, JNOV is an extreme remedy which is properly
    entered by the trial court only in a case where, after viewing the
    evidence in the light most favorable to the verdict winner, the
    facts are so clear that no two reasonable minds could fail to
    agree that the verdict, as rendered by the jury, was improper.
    JNOV, however, may not be employed to invade the province of
    the jury. Thus, when there is a question of fact to be resolved, it
    is within the sole purview of the jury. JNOV should not be
    entered where evidence is conflicting upon a material fact.
    Thus, where the jury has been presented with conflicting
    evidence, a motion for JNOV should be denied.
    Rohm & Haas Co. v. Cont'l Cas. Co., 
    732 A.2d 1236
    , 1248 (Pa. Super.
    1999) (emphasis in original), affirmed, 
    781 A.2d 1172
    (Pa. 2001).
    Appellants’ first three assertions of error challenge the trial court’s
    decision to admit evidence of industry safety standards, OSHA safety
    standards, and Mr. Renninger’s alleged assumption of risk.          “Questions
    concerning the admission and exclusion of evidence are within the sound
    discretion of the trial court and will not be reversed on appeal absent an
    abuse of discretion.” B & L Asphalt Indus., Inc. v. Fusco,

    For many years, our law prohibited the introduction of industry
    standards evidence in a strict liability case, the rationale being that under
    § 402A of the Restatement (Second) of Torts,7 “it is the product itself which
    is on trial, and not the manufacturer’s conduct.”     Lewis v. Coffing Hoist
    Div., Duff-Norton Co., Inc., 
    580 A.2d 590

    Section 402A provides:
    § 402A Special Liability of Seller of Product for Physical Harm to
    User or Consumer
    (1) One who sells any product in a defective condition unreasonably
    dangerous to the user or consumer or to his property is subject to
    liability for physical harm thereby caused to the ultimate user or
    consumer, or to his property, if
    (a) the seller is engaged in the business of selling such a
    product, and
    (b) it is expected to and does reach the user or consumer
    without substantial change in the condition in which it is sold.
    (2) The rule stated in Subsection (1) applies although
    (a) the seller has exercised all possible care in the preparation
    and sale of his product, and
    (b) the user or consumer has not bought the product from or
    entered into any contractual relation with the seller.
    Restatement (Second) of Torts § 402A.
    - 14 -
    J-A23029-16
    (Wash. 1984)).      Furthermore, “if a manufacturer’s product has design
    attributes which make it unsafe for its intended use, there is no relevance in
    the fact that such a design is widespread in the industry.” 
    Id. In other
      words,   Lewis   espoused   a   strict   separation   between
    negligence principles and strict liability causes of action. The Lewis Court
    gleaned that principle from Azzarello v. Black Bros., Co., 
    391 A.2d 1020
    ,
    1023 (Pa. 1978), which our Supreme Court in Tincher expressly overruled.
    
    Tincher, 104 A.3d at 335
    . Under Azzarello, the trial court decided, as a
    matter of social policy, whether a product was unreasonably dangerous,
    within the meaning of § 402A. 
    Id. at 367.
    If the trial court found a product
    unreasonably dangerous, it submitted the case to a jury, which then
    determined whether plaintiffs proved the allegations in their complaint by a
    preponderance of the evidence. 
    Id. The Tincher
    Court noted: “[f]ollowing
    Azzarello, decisional focus in strict liability cases shifted to reflect an
    increasing concern with segregating strict liability and negligence concepts.”
    
    Id. The Tincher
    Court went on to discuss Lewis in detail, but it did not
    expressly overrule Lewis, or any case other than Azzarello.          See 
    id. at 368-69.
    The Supreme Court wrote:
    We recognize—and the bench and bar should recognize—
    that the decision to overrule Azzarello and articulate a standard
    of proof premised upon alternative tests in relation to claims of a
    product defective in design may have an impact upon other
    foundational issues regarding manufacturing or warning claims,
    and upon subsidiary issues constructed from Azzarello, such as
    the availability of negligence-derived defenses, bystander
    compensation, or the proper application of the intended use
    - 15 -
    J-A23029-16
    doctrine. These considerations and effects are outside the scope
    of the facts of this dispute[.]
    
    Id. at 409
    (emphasis added).
    Ultimately, the Tincher Court held that a plaintiff may show a
    defective condition by showing either that “(1) the danger is unknowable
    and unacceptable to the average or ordinary consumer, or that (2) a
    reasonable person would conclude that the probability and seriousness of
    harm caused by the product outweigh the burden or costs of taking
    precautions.”    
    Id. at 335.
       These tests present issues of fact for a jury,
    except where it is clear that reasonable minds cannot differ on an issue. 
    Id. Presently at
    issue in this design defect case is the second of these
    tests, known as the risk-utility test.    Throughout its Tincher opinion, the
    Supreme Court noted that the risk-utility test is derived from negligence
    principles.     Specifically, the Court quoted then-Justice Saylor:                “In
    application to design defect claims, the concurrence […] observed, courts in
    Pennsylvania recognized ‘an integral role for risk-utility (or cost-benefit)
    balancing, derived from negligence theory.’” 
    Id. at 371
    (quoting Phillips v.
    Cricket   Lighters,    
    841 A.2d 1000
         (Pa.   2003)   (OAJC)   (Saylor,    J.
    concurring)); see also 
    id. at 373-74
    (quoting Bugosh v. I.U. North Am.,
    Inc., 
    971 A.2d 1228
    (Pa. 2009) (Saylor, J., joined by Castille, C.J.,
    dissenting)).    Justice Saylor opined that a higher threshold of fault is
    appropriate in design defect cases, where a plaintiff’s verdict suggests that
    an entire product line is defective.     
    Id. Further, the
    Court noted that the
    - 16 -
    J-A23029-16
    Lewis Court’s distinction between negligence and strict liability principles
    was in “harmony” with Azzarello. 
    Id. at 368.
    Despite the Supreme Court’s apparent recognition that the effects of
    Tincher would be far reaching, and despite its analysis of the negligence
    underpinnings of the risk-utility test Appellants rely upon in this case,
    Appellants largely sidestep the issue: “Nowhere in the Tincher decision did
    the Pennsylvania Supreme Court allow for the consideration of negligence
    principles in products liability cases.” Appellants’ Brief at 13. Appellants cite
    pages 399 and 410 of Tincher as evidence that the Supreme Court
    “specifically refused to adopt a theory of products liability which included
    negligence theory and principles.” 
    Id. at 15.
    On page 399 of Tincher, the
    court recognized the limits of Dean Wade’s seven-part analysis, and
    recognizes the shortcomings of the risk-utility test.    
    Tincher, 104 A.3d at 399
    .   Nowhere does the Court state that negligence principles will not be
    relevant in a case where a plaintiff relies on risk-utility to establish a
    defective product. Likewise, on page 410, the Tincher Court explains some
    of its reasons for declining to adopt the Third Restatement.        
    Id. at 410.
    Nothing on page 410 supports a conclusion that the Tincher Court intended
    to maintain a strict division between negligence and strict liability principles
    in the risk-utility test.   Indeed, on the prior page (quoted above with
    emphasis added) the Supreme Court recognized that its holding could have
    - 17 -
    J-A23029-16
    an impact on, among other things, the availability of negligence-based
    defenses. 
    Id. at 409
    .
    With this background, we now turn to the specifics of Appellants’
    argument.     Appellants’ filed a pretrial motion in limine seeking to exclude
    evidence of industry standards applicable to casters of the type at issue in
    this case and OSHA standards applicable to the Commodore plant where Mr.
    Renninger worked.         The trial court denied the motion, reasoning that
    “[industry] standards may supply the jury with a useful starting point from
    which to evaluate the caster’s design.” Trial Court Opinion, 4/17/2015, at
    21.8   As described above, Appellee introduced evidence of ANSI standards
    governing casters.       Hutter testified that no industry standard required the
    use of toe guards on casters.           Appellee, through Hutter, also introduced
    evidence     of   OSHA     violations    at    Commodore,   and   safety   measures
    Commodore could have taken to prevent Mr. Renninger’s injury, and
    evidence of Mr. Renninger’s assumption of risk.
    ____________________________________________
    8
    Appellee argues in its brief that Appellants opened the door to industry
    standards evidence because their expert was the first to address it at trial.
    This argument is not well taken. After their unsuccessful motion in limine,
    Appellants had the right to devise an appropriate trial strategy.           See
    Sprague v. Walter, 
    656 A.2d 890
    , 906 (Pa. Super. 1995) (“Having received
    an unfavorable ruling on its motion to exclude all such evidence, [the party]
    was entitled to use that evidence to its best advantage in order to try to win
    the case, and not be forced to wait for possible vindication of the trial court’s
    adverse ruling.”).
    - 18 -
    J-A23029-16
    Surprisingly, Appellants do not address Hutter’s discussion of industry
    standards governing casters, or even cite to portions of the record where
    Hutter offered that testimony.             Appellants used the phrase industry
    standards in their question presented and again in their brief, but they
    confined the substance of their record citations and legal argument to the
    evidence of Commodore’s conduct and OSHA violations.9 Appellants’ Brief at
    12, 21. We will therefore do the same. See Pa.R.A.P. 2119(c) (requiring
    appellants to support arguments with pertinent citations to the record).

    This argument is consistent with Appellants’ counsel’s argument during
    the colloquy on the proposed points for charge:
    APPELLEE’S COUNSEL: We do request 25 and 26 or an amalgam
    of the two so that they realize it is relevant to consider the
    industry standards that they’ve heard about. It’s not a
    dispositive, but it’s relevant as to whether or not a seller
    acted reasonably.
    APPELLANTS’ COUNSEL: Compliance with industry standards,
    you were talking about industry standards with regard to
    workplace not with regard to the product.
    APPELLEE’S COUNSEL: No. We talked about it with regard to
    the product too. It doesn’t violate any industry standards.
    That was pretty clearly said by Dr. Hutter.
    APPELLANTS’ COUNSEL: No.
    APPELLEE’S COUNSEL: No, it wasn’t.
    APPELLANTS’ COUNSEL:               He   covered   employer   employer
    employer.
    N.T. Trial, 6/25/2015 a.m., at 30-31.
    - 19 -
    J-A23029-16
    Concerning Commodore’s conduct, and the alleged OSHA violations,
    Appellants cite three specific portions of the trial transcript. Appellants’ Brief
    at 12, 21. First, at pages 178 through 181 of the June 24, 2015 transcript,
    Hutter discussed the lack of safety shoes, trained industrial truck operators,
    and spotters, the uneven floor, and other potential hazards at the
    Commodore plant. N.T. Trial, 6/24/15, at 178-81. Hutter also explained his
    reasons for opining that a toe guard would not necessarily prevent the type
    of injury Mr. Renninger sustained. 
    Id. Next, Appellants
    cite pages 191 to 196 of the June 24, 2015 transcript.
    Appellants’ Brief at 12, 21. On these pages, Hutter further elaborated on his
    reasons for believing a toe guard would not necessarily prevent a foot injury.
    N.T Trial, 6/24/15, at 191-92, 195-96. Likewise, Hutter further elaborated
    on his opinion that Commodore failed to provide proper supervision and
    footwear. 
    Id. at 193.
    Hutter stated that Commodore was cited for an OSHA
    violation as a result of these deficiencies. 
    Id. at 193-195.
    Finally, Appellants cite pages 198-99 of the June 24, 2015 transcript,
    wherein Hutter testified that Mr. Renninger’s injury was a result of
    Commodore’s     OSHA    violations   and   Mr.   Renninger’s   own   negligence.
    Appellants’ Brief at 12, 21; N.T. Trial, 6/24/15, at 198-99. As noted above,
    in none of these portions of the transcript did Hutter reference industry
    standards applicable to casters.
    - 20 -
    J-A23029-16
    Appellants rely in part on Sheehan v. Cincinnati Shaper Co., 
    555 A.2d 1352
    (Pa. Super. 1989), appeal denied, 
    564 A.2d 1261
    (Pa. 1989). In
    Sheehan, as in the instant case, the defendant argued that the plaintiff’s
    employer’s OSHA violations were relevant to causation. The defendant sold
    a shear to the plaintiff’s employer and argued that OSHA regulations
    required the employer to provide safety guards for use with the shear. 
    Id. at 1354.
    We rejected the defendant’s argument:
    Although Shaper attempts to couch its argument in terms
    of causation, it fails to explain how OSHA standards are relevant
    to that issue. The essence of Shaper’s argument is that Shaper
    acted reasonably by designing the shear without a safety guard
    since OSHA standards place the responsibility of providing a
    safety guard on the buyer/employer.
    [***]
    We conclude that the OSHA regulations proffered would
    introduce into a strict liability action the reasonableness of
    Shaper’s failure to provide the new safety device for this
    machine, an issue irrelevant to whether liability attaches.
    Accordingly, the trial court did not err by sustaining Sheehan's
    objections to the introduction of this evidence.
    
    Id. at 1354-55.
    Thus, the Sheehan Court employed the strict separation
    between negligence and strict liability, set forth in Lewis in “harmony” with
    Azzarello.    See 
    Tincher, 104 A.3d at 368
    (discussing Lewis and
    Azzarello).
    Likewise, Appellants cite Majdic v. Cincinnati Mach. Co., 
    537 A.2d 334
    (Pa. Super. 1988) (en banc), to support their argument that a plaintiff’s
    employer’s conduct is not relevant in a strict products liability action. The
    - 21 -
    J-A23029-16
    plaintiff operated a power press used for “the punching, stamping, bending,
    or sheering of metal.” 
    Id. at 336.
    There, the defendant provided a press
    brake, which plaintiff’s employer then incorporated into its manufacturing
    system.     
    Id. at 336-37.
       Plaintiff alleged the press brake was defective
    because “it did not contain a guard which would have prevented the
    operator’s hands from entering the point of operation.”            
    Id. at 336.
      The
    defendant    argued   that    “the    press      brake   was   a   general   purpose,
    multifunctional unit which was unequipped with dies and had no point of
    operation when sold.” 
    Id. at 337.
    Thus, “only [plaintiff’s employer], which
    incorporated the press brake into its manufacturing system, could determine
    and install the guards and warnings necessary for the particular function
    assigned to the press.”      
    Id. The defendant
    introduced evidence of ANSI
    standards for power presses and evidence that it was industry custom for
    the purchaser of a press brake to provide the necessary safety devices. 
    Id. at 338.
       Citing Lewis, decided the year before Majdic, the Majdic Court
    held that the trial court erred in permitting the ANSI evidence and evidence
    of industry custom.     
    Id. at 338-39.
              The Majdic Court rejected such
    evidence because it implicated the reasonableness of the manufacturer’s
    conduct.
    Appellants do not address whether Tincher has any implications for
    the continued vitality of Sheehan or Majdic.             Assuming without deciding
    that the trial court erred in admitting evidence of Commodore’s conduct
    - 22 -
    J-A23029-16
    under those two cases, we conclude the trial court’s error was harmless. “To
    constitute reversible error, a ruling on evidence must be shown not only to
    have been erroneous but harmful to the party complaining.” B & L Asphalt
    Indus., 
    Inc. 753 A.2d at 270
    . “An evidentiary ruling which did not affect
    the verdict will not provide a basis for disturbing the [fact-finder]’s
    judgment.” 
    Id. 270-71. The
    trial court instructed the jury that Commodore’s conduct was
    relevant only if the jury deemed it a superseding cause of Mr. Renninger’s
    accident. N.T. Trial, 6/25/2015 p.m., at 15; Verdict Slip, Question 3. We
    presume that juries follow the trial court’s instructions. Maya v. Johnson
    and Johnson, 
    97 A.3d 1203
    , 1222 (Pa. Super. 2014), appeal denied, 
    112 A.3d 653
    (Pa. 2015).     Question one on the verdict slip asked the jury
    whether the caster was defective. Question three on the verdict slip asked
    the jury to assess whether Commodore’s or Mr. Renninger’s conduct was a
    cause of the accident. The jury answered question one in the negative, and
    therefore left question three blank.   Given the foregoing, we will presume
    that the jury did not consider the evidence of Commodore’s conduct or Mr.
    Renninger’s alleged assumption of risk.
    In addition, the record contains a significant body of evidence
    supporting the jury’s verdict.   As we have already explained, the jury had
    before it Appellee’s introduction of ANSI standards governing casters, which
    Appellants have not challenged on appeal.    Further, the jury had before it
    - 23 -
    J-A23029-16
    Appellee’s evidence that toe guards would not have protected Mr. Renninger,
    given the uneven flooring in Commodore’s plant. The jury also had before it
    Appellee’s evidence that toe guards would pose risks such as severing
    electric cords draped across the floor. Given all of this evidence, and given
    the trial court’s instruction that Commodore’s and Mr. Renninger’s conduct10
    was relevant only to causation, we conclude that any error in admitting
    evidence of Commodore’s conduct was harmless.
    We pause here to address the parties’ arguments under Tincher.
    Appellants take a very narrow reading of Tincher, seemingly concluding that
    it overruled Azzarello but did little else. Even a cursory reading of Tincher
    belies that argument. The Supreme Court’s opinion in Lewis, providing for
    a strict separation between negligence and strict liability, was, according to
    the Tincher Court, a result in harmony with Azzarello. The Tincher Court,
    as we have explained, did not expressly overrule Lewis, and had no
    occasion to do so based on the arguments the parties presented to it. The
    Tincher Court did anticipate that its holding would have significant ripple
    effects to be addressed case by case as they arise:

    foundational or subsidiary considerations and consequences of
    our explicit holdings.      In light of our prior discussion, the
    difficulties that justify our restraint should be readily apparent.
    The common law regarding these related considerations should
    develop within the proper factual contexts against the
    background of targeted advocacy.
    
    Tincher, 104 A.3d at 410
    (emphasis added).
    Ordinarily, this Court is bound by Supreme Court precedent, as well as
    the published decisions of prior en banc and three-judge panels of this
    Court. In the wake of Tincher, however, the bench and bar must assess
    the Tincher opinion’s implications for a large body of post-Azzarello and
    pre-Tincher case law.
    In this case, Appellee argues that the Tincher Court’s reliance on
    California case law, particularly Barker v. Lull Engineering Co., 
    573 P.2d 443
    (Ca. 1978) reveals the Supreme Court’s intent to admit evidence of
    industry standards because California does so. Appellee’s Brief at 12-13. In
    fact, admission of industry standards evidence is still in controversy in
    California, and the issue is currently pending before the California Supreme
    Court. Kim v. Toyota Motor Corp., 197 Cal. Rptr. 3d (Cal. Ct. App. 2016),
    review granted and opinion superseded, 
    368 P.3d 311
    (Cal. 2016).
    In Kim, the plaintiffs filed a motion in limine to preclude evidence of
    industry custom and practice concerning the design of their 2005 Toyota
    Tundra pickup truck. 
    Id. at 652.
    Plaintiffs argued that electronic stability
    control (“ESC”) could have prevented their accident.        Toyota’s product
    manager acknowledged that Toyota engineers recommended making ESC
    - 25 -
    J-A23029-16
    standard on the 2005 Tundra. 
    Id. at 653.
    Toyota instead offered it as an
    option, noting that no other manufacturer of full-size pickup trucks offered
    ESC as a standard feature in 2005. 
    Id. The Kim
    Court noted two lines of
    California case law arriving at different conclusions on the admissibility of
    industry standards evidence, and devised a middle ground approach. 
    Id. at 655-61.
    The California Supreme Court has yet to render a decision in Kim.
    Kim is illustrative of some of the competing arguments for and against
    industry standards evidence in strict products liability/design defect cases.
    Other states, including Illinois, hold that evidence of a product’s compliance
    with industry standards is relevant, but not a complete defense.          See
    Jablonski v. Ford Motor Co., 
    955 N.E.2d 1138
    , 1154 (Ill. 2011). Neither
    party to the instant appeal has offered any substantive argument for or
    against the admission of such evidence in Pennsylvania after Tincher.
    Given the arguments before us, we do not have occasion to express an
    opinion. In light of all of the foregoing, Appellants’ first three arguments do
    not merit relief.
    Appellants’ next three assertions of error address the trial court’s jury
    instruction.
    We will reverse for improper jury instructions only where
    the trial court committed a clear abuse of discretion or an error
    of law which controlled the outcome of the case. […] We will
    not reverse for isolated inaccuracies; the charge as a whole must
    be shown to have caused prejudicial error. Thus, to constitute
    reversible error, a jury instruction must be erroneous and
    harmful to the complaining party.

    Schaaf v. Kaufman, 
    850 A.2d 655
    , 666 n.10 (Pa. Super. 2004) (internal
    citations and quotation marks omitted).
    Appellants argue that the trial court erred in instructing the jury on the
    so-called “Dean Wade” factors.11               Dean Wade developed seven factors
    relevant to application of the risk-utility theory of recovery.       The Tincher
    Court referenced the Dean Wade test, noted its limitations, and did not
    expressly adopt it.      
    Tincher, 104 A.3d at 389-90
    . As both the trial court
    and Appellee note, Appellants failed to object to the jury instruction in
    question.    Appellants’ do not cite the place of preservation of this issue in
    accord with Pa.R.A.P. 2117(c), and our review of the transcript does not
    reveal any specific objection to a charge containing the seven Dean Wade
    factors. Appellee’s proposed points for charge number 22 included six of the
    Dean Wade factors, and when the parties addressed that point the trial court
    simply noted it was covered in the court’s risk utility instruction. N.T. Trial,
    6/25/2015 a.m., at 30. The Dean Wade factors were mentioned during the
    colloquy, but it is not clear that Appellants’ objected to a charge containing
    the seven factors. 
    Id. at 29.
    At the conclusion of its charge, the trial court
    offered the parties the opportunity to raise “any matters concerning the
    charge” and Appellants offered nothing.            N.T. 6/25/2015 p.m., at 27.   As
    such, they have waived this argument. “Objections to jury instructions must

    , 292 (Pa. 2014).              “[W]here a party fails to
    specifically object to a trial court’s jury instruction, the objection is waived
    and cannot subsequently be raised on appeal.” Cruz v. Ne. Hosp., 
    801 A.2d 602
    , 610–11 (Pa. Super. 2002) (quoting Randt. v. Abex Corp., 
    671 A.2d 228
    , 232 (Pa. Super. 1996)).         Furthermore, Appellants’ brief does not
    address any particular factor or factors and explain how it prejudiced their
    case.
    Next, Appellants argue the sequencing of the trial court’s instructions
    was erroneous because it permitted the jury to reach a decision on product
    defect without considering the risk-utility test.      Once again, the record
    reveals that Appellants failed to lodge a timely objection.
    In their sixth assertion of error, Appellants claim the trial court erred
    in declining to instruct the jury on the intended-use doctrine.      The parties
    dispute whether the intended use doctrine—which holds that a product must
    be safe for its intended use by its intended user—applies after Tincher.
    Instantly, there is nothing to suggest that Mr. Renninger’s injury occurred
    during an unintended use of the caster, or that the persons moving the
    home along the plant floor were unintended users.             To the extent they
    believe the alleged conduct of Commodore and/or Mr. Renninger was offered
    as evidence of an unintended use of the caster (see Appellants’ Brief at 14-
    - 28 -
    J-A23029-16
    15), we have already explained that the jury never considered that
    evidence.       As noted above, Appellants cannot obtain relief unless they
    demonstrate that the trial court’s instruction was erroneous and harmful.
    Appellants have not explained how the court’s instruction harmed their case,
    and that omission is fatal to this argument.
    Finally, Appellants argue that the trial court erred in entering summary
    judgment on Appellants’ failure to warn and manufacturing defect causes of
    action.      Appellants’ argument on this point is puzzling, in that Appellants
    address an evidentiary dispute as to which party was responsible for the
    design of the caster assembly. Appellants’ Brief at 23-24. Appellants fail to
    explain how this evidentiary dispute was relevant to their failure to warn and
    manufacturing defect claims, or precisely why the trial court erred in
    entering summary judgment on those claims. This argument does not merit
    relief.
    In summary, we have concluded that none of Appellants’ assertions of
    error merits relief. We therefore affirm the judgment.
    Judgment affirmed.
    Judgment Entered.
