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 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.
