Install Considerations

1. Strikes were rarely used with full mortise locks. Typically wood is notched to accept bolt. However if preferred a generic #4521 strike is available separately.
2. When using on doors: use on right and left hand doors. Place lock to account for keyhole location.
3. When using on drawers: Keyholes are off-center requiring lock to be positioned accordingly.
4. Lock fits into cut out pocket in top-edge of drawer or side-edge off door.  Once installed only brass selvedge and keyhole are exposed. 

If replacing a lock: the backset measurement must be determined

• If you have original lock: measure distance between top edge of lock to lock pin in center of keyhole. This measurement is known as the backset.
• If old lock not available, determine backset by measuring: distance from center of keyhole (where lock pin would be) to top edge of drawer or side edge of door.
• The backset measurement of the replacement lock, must match backset measurement in original lock and/or keyhole location measurement in drawer or cabinet door.
