- Mark the four A locations for the trim holes.
- Drill 3/8-inch diameter holes through the trim side only at the four marked locations.
- For 02CM models, mark and drill a 3/8-inch (1/2-inch max) hole straight and level through the door at the specified location (5 inches down, 0.688 inches offset).
Trim installation
For 02CM (Trim with pull):
- Place the trim onto the door.
