Once the holes are drilled and the notch cut, the next step is to bolt the rotary latch to the adapter panel by sliding the latch from the bottom up under the bracket as shown. Bolt the latch to the bracket with two 1/4-20x1/2-inch button-head cap screws. Tighten the screws with a 5/32-inch Allen wrench. Then, reinstall the adapter panel/latch assembly using the No. 10 stainless sheetmetal screws supplied in the kit.
