1. Mounting of locks in door frame
The lock is mounted in the frame in the mounting holes .
The holes are drilled and threaded as shown below. We
recommend you to use one of our adapter plates when re-
placing a lock with different hole pattern.
2. Adjustment of lock engagement and clearance
The door lock should be adjusted so that the latching bolt engage-
ment is 15 mm. According to standard EN81-20, the minimum per-
missible locking is 7 mm + movement with closed contact (approx.
2 mm). The locking engagement is adjusted by moving the lock in
the holes 1 (see Figure 1).
The lock is adjusted so that there is clearance at the latching bolt and
the door leaf in locked position. We recommend a clearance of 1-2
mm. If necessary, washer/distance bush can be placed between the
lock and the frame if the clearance is too large.
