Figure 2-123. Fabrication of Backstrap Keeper.
(f) Install a socket assembly in the center of the folded end and a stud assembly in the center of the
reinforcement duck, as shown in figure 2-124. Use the following installation procedure.
1 Cut the fabric for the socket and stud assemblies using a mallet and lead cutter block and an
appropriate sized double- or single-bow cutter (see figure 2-125).
2 Installation of a snap fastener may be performed by three different methods. The most
common method is the hand-held method that requires the use of a leather mallet (figure 2-
125) or other non-steel impact device, a holder to hold the appropriate sized chuck (A, figure
2-126), and an anvil which is used to contain a compatible sized die. A second method of
installing a snap fastener assembly is by use of the hand-operated press (B, figure 2-126).
The hand-operated press is a lever-type device that can accommodate an appropriate sized
chuck and die. When installed in the hand-operated press, the chuck and die are Individually
secured in position by a threaded screw that is tightened using a suitable sized key (Allen-type
hexagon wrench) or a flat-tip (common-head) screwdriver, as applicable. The third method of
snap fastener Installation is by use of the foot-operated press which, except for the means of
operation, functions similar to the hand-operated press.
