What is a surface-mounted cabinet lock?
Surface-mounted locks are designed for cabinet and furniture doors only. This style cannot be used on drawers, desk lids, or boxes.
They are easy to install as lock mounts directly to inside face of door. No mortise or cut out pocket is used for this style lock.
Our surface locks are reversible for use on right- or left-hand doors.
On glass-front doors, the lock body may be visible through the glass. If you prefer a less visible installation, consider a half-mortise or full-mortise lock.
Use with a keyhole cover for a finished appearance.

- Keyhole location determines required backset measurement for lock.
- Backset: distance between selvedge-edge of lock to center-of-pin in keyhole. (see diagram)
- Be sure overall size of Lock-Plate will fit onto door stile/face frame
How do I measure for a replacement lock?
- If you have original lock: measure distance between selvedge-edge (edge where bolt shoots through lock) to lock pin in center of keyhole. This measurement is known as the backset.
