Mark centerlines
Caution:
If the door is a fabricated hollow metal door,
determine whether it is properly reinforced to support the
lock. If door reinforcement is not adequate, consult the door
manufacturer for information on proper reinforcement.
Note:
Prepare the door according to ANSI A115.1 before using these
instructions.
1 Mark the horizontal centerline of the lock on both sides of the door
and on the door’s edge.
2 Mark the vertical centerline of the lock on the door edge.
3 Mark the vertical centerline of the cylinder and knob/lever on both
sides of the door as measured from the vertical centerline on the
door’s edge.
4 Mark the horizontal centerline of the strike on the door jamb 3/8"
above the horizontal centerline of the lock.

Install strike plate
1 Mortise the door jamb for the strike box and strike plate. When the
strike box is not used, mortise the jamb deep enough to allow the
latchbolt and deadbolt to fully extend. (See
Installation Specifications
for dimensions, template H03 and H11.)
2 Insert the strike box and secure the strike with screws provided.
Caution:
The auxiliary bolt must make contact with the strike
plate. The auxiliary bolt deadlocks the latchbolt and prevents
someone from forcing the latch open when the door is closed.
If the incorrect strike is installed, a lock-in can occur.
