Install strike box and strike plate
1 In alignment with the center of the latchbolt, mortise
the door jamb to fit the strike box and strike plate.
2 Drill the holes for the screws used to install the strike
box and strike plate.
3 Insert the strike box and secure the strike with the two
screws provided.
4 Check the position of the deadlocking plunger against
the strike plate.
Caution:
The deadlocking plunger of the latchbolt
must make contact with the strike plate, as shown
in Figure 6b. The plunger deadlocks the latchbolt
and helps prevents someone from forcing the
latch open when the door is closed.
