Installation Instructions for B.A.S.I.S. Cylindrical Locks
Preparing the door and door jamb
5 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 5b. The plunger deadlocks the latchbolt
and prevents someone from forcing the latch
open when the door is closed.
