centered on the plate. There is no top or
bottom to worry about.

guide alignment pin and tighten to door.
Alternate tightening between the top and
bottom clamp. Do not attempt to tighten one
clamp all the way at once.
With a 3/8” twist drill,

holes on both sides
of the door. These
holes go to the mor-
tise cavity. Do not try
to drill from one side
through to the other.
