MODEL 500/505 INSTALLATION INSTRUCTIONS
The model 500/505 is intended to replace the conventional door furniture fitted
to an existing mortice latch, or an existing mortice lock which has both a spring
latch and a deadbolt. The square follower should be 8mm square. Any lock and
key mechanism is retained to operate the deadbolt. The latchbolt will only
operate by code, and NOT by key.
A mortice lock case should have holes for fixing bolts to pass through on either
side of the square latch follower and sometimes, additionally, a hole below the
follower. See figure 1 and confirm that your lockcase is compatible with the
500/505 lock plates.
