Step 3 - install the paddle latch
Print this template, and ensure that the line at the top is 4" long. If the line isn't 4" long, enlarge or reduce the drawing to get the size correct.
Fold the template at the line, and position the line at the top of the box as shown. Using a center punch, mark the center of the hole for the lock cylinder, and the center of each corner radius. Drill a 1/8" pilot hole at each point you punched. The easiest way to make the hole for the lock cylinder is with a 3/4" hole saw or a step drill with a 3/4" step. The easiest way to make the large hole is by drilling the 4 corners with a step drill with a 1/2" step or a 1/2" hole saw, and then cut the straight lines with a metal cutting blade in a handheld jig saw.
Ensure the lock cylinder and paddle handle fit well in the holes; adjust holes with a file if necessary. Once everything fits well, mark the rivet holes for the paddle handle, center punch the locations and drill 3/16" holes for the pop rivets. Pop rivet the paddle handle in place and then install the lock cylinder.
