Calculating Stud Length
RECEPTACLES
TOTAL PILEUP = Panel + Support + Gap
Total Pileup Drawing
  1. First calculate the total pileup. Add Panel thickness + Support thickness + Gap thickness.
    NOTE: The gap is the distance between the panel and the support, and it may be the result of panel and support shape, use of a grommet or other stud retainer, or by use of a spacer. The Gap Thickness dimension will equal zero when the panel surface is flush to the support surface. For example, Gap = 0 when the underside of the panel is counter bored to accept the thickness of the stud retainer.
  2. Using the calculated total pileup for the chosen receptacle, locate your total pileup in one of the ranges in the table below and find the Stud Grip size to the left. The Stud Grip is added to the end of the stud part number. For example: in the stud part number "121J-6550-Z3CT", the Stud Grip is "50".
