Full Mortise Lock Measurement Diagram

Drop In Locks  are authentic replacements for furniture made in the 1900's. Use on drawers and doors hinged on the right. Designed to drop into a pocket cut by a router or machine. Once installed lock should fit tightly. It will be encased with wood on both sides only selvedge edge will show. 

This is a very reasonably priced lock, as such: locking mechanism is average, not as smooth as finer made brass locks, yet is serviceable. Made in Asia.

Replacing Full Mortise 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.

It dropped in.

Julian Perrin
Lock fit perfectly

The drop in lock fit the existing secretary drop desk but I am concerned that the lock bolt easily pushes back down without the key. This may cause the desk to drop on its own

Great product

Drop-in Locks

I am restoring a secretary that is about 100 yrs. old. The locks matched the old ones very well.

Drop In Locks - Drop In Locks, Backset 3/4

The locks were what I was looking for, but they do not work as expected. The bolt does not lock in the locked posistion. You can push it back down with light pressure. The original locks on my piece cannot be pushed back down, and the key is needed to open.
