Surface Lock Information
Surface Locks are used on furniture and cabinet doors. Easy to install
: No mortising is required as lock mounts directly to the inside of the cabinet door.
A strike is rarely used as it can impede the bolt from smoothly extending behind face frame or door stile.
Our surface locks are reversible meaning they will work both right and left hand doors.
Please note: these locks are visible when looking into a glass curio or china closet door. If preferred a half mortise or full mortise lock will provide a less visible alternative.
When measuring consider:
Backset: distance between: selvedge-edge of lock to center-of-pin in keyhole. (see diagram on right)
When replacing locks: the backset is most crucial as it must match cutout in furniture for lock to line up correctly with existing keyhole
Be sure overall size of Lock-Plate will fit onto door stile/face frame
When installing consider:
Determine desired location of lock
Position of lock must allow for bolt to extend behind face frame of cabinet. A minimum of ¼" is necessary to secure door when locked.
Ideally edge of lock should line up with edge of door
If keyhole already exists in door, make sure lock-keyhole lines up with cabinet-keyhole
Measure distance from top of lock-plate to center of key pin
Measure distance from side of lock-plate to center of key pin
With these two measurements locate keyhole on furniture front, make sure key pin is aligned with keyhole location
Drill small pilot hole at key pin location, hold lock in position and check to make sure hole lines up with key pin
Drill hole larger to accommodate key barrel
Cut remaining portion of keyhole with a small keyhole saw
Mark location of lock on door interior
Insert key from front through door into lock
With key in position, hold lock at desired location on back of door and mark screw holes
Drill small pilot holes for screws
Mount lock and attach with wood screws
For a finished appearance: mount an escutcheon/keyhole plate, on door front.
