Replacing Box Locks

Keyhole location measurement is critical. Replacement lock-keyhole-location must match location of keyhole in furniture.

To measure: easiest to measure old lock, if you have it:

• Lock Keyhole Location: distance between selvedge-edge - where bolt shoots through, to lock pin. This measurement is known as the backset.
• Furniture Keyhole Cutout Location: distance between furniture-edge to estimated location of lock pin in furniture keyhole.
