Choosing the right size:
Mortice locks are sized by the depth of the lock case and the rectangular hole - "the mortice" - into which the lock fits.
If you are replacing an existing mortice lock you can find our what size you need without removing the old lock.
Simply measure from the edge of the door to the center of the keyhole, If the measurement is 45mm ( 1 3/4" ) you need 65mm ( 2 1/2" ) mortice lock. If the measurement is 57mm ( 2 1/4" ) you need a 76mm ( 3" ) mortice lock.
