If a stripper plate is used, caution must be used to make sure the screw does not enter the travel area as shown in drawing provided. Cap screws may be used for holding the stripper plate, however, this would require a much thicker plate to accommodate the thicker head on the screw. Some users save additional time and money by only attaching a portion of the assemblies to the stripper plate, provided the design is suitable.
