    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.

      Restoring an 80 year old carpenter's tool chest. It was missing the original lock. This one fit great.

      The lock mechanism is good quality and matched the old damaged antique lock almost perfectly.
