    We recommend reading: Selecting and replacing half mortise locks.

    Many lock sizes were made years ago. Few sizes are now made. Replacing old locks often requires cabinet work.

    Lift Lid Box Locks are only visible from box interiors. They are a small half mortise type requiring lock to be fitted into a cut out indentation in wood, on interior of case. Strike attaches underneath surface of lid. Once installed lock plate is only seen on inside of box.  Strike drops down into lock when lid is closed. 

    Use on small chests with a lift lid. These are hard working, solid brass locks. Made in England.

    Replacing Box Locks

    Keyhole location measurement is critical. Replacement lock-keyhole-location must match location of keyhole in furniture.

    To measure: easiest to measure old lock, if you have it:

    • Lock Keyhole Location: distance between selvedge-edge - where bolt shoots through, to lock pin. This measurement is known as the backset.
    • Furniture Keyhole Cutout Location: distance between furniture-edge to estimated location of lock pin in furniture keyhole.
