Align the center line (CL) of the
lock body template with the CL of
the door leaf. Ensure the CL of the
strike plate template matches the lock
body CL as closely as possible.

Cut out mortise holes for the lock
body and strike plate and drill holes
according to the templates.

Tighten the fixing lugs with
screws.
