Half Mortise Box Lock Measurement Diagram

Lift Lid Box Locks are an excellent choice for small chests or boxes. Locks are solid brass with accurate construction. Made in England.

When installing: half mortise lock is mortised flush with wood on box interior. Strike attaches underneath surface of lid. Once installed lock plate shows on interior. Keyhole is all that is seen of exterior of box. When closing lid, strike drops down into lock. Lock mechanism is engaged with key. Backset measurement is  3/4".

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.

Brass lock

I use these locks for a 9'x15' walnut doved tailed box. This is the 4th or 5th time I have used this style lock and they are perfect and unique.
