• When using on doors: select according to side door is hinged on. This lock is for cabinet doors hinged on right.
• When using on drawers: Keyholes are off-center requiring lock to be positioned accordingly.
• A half mortise lock installs into a partial cut out in furniture. In closed position, lock is not seen. 
  

If replacing a lock: the backset measurement must be determined

• If you have original locks: 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 will 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.
