    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.

    The locks from Paxton Hardware are very good quality.

    High Quality

    Your specs on the website were detailed to the point that I had full confidence that the lock would fit my application. I received the order in a timely manner and found it to be of high quality and it fit perfectly.

    Cabinet Lock

    The lock works perfectly, unfortunately, the faceplate, strike plate and key does not come in oil rubbed bronze and they key is plated, so I was unable to age the finish.
