Door Jamb Preparation
Prepare the door jamb – use the strike plate as a template to drill 1/8" screw holes and chisel out the mortise. The
strike plate must t ush with the surface of the door jamb.
NOTE: If your door is pre-drilled, check the hole sizes to make sure they are the proper size. If they are the proper
size, skip to Step 3.
