Full Mortise Lock
Lock Size
| Finding an exact match for an old lock is not always possible, as only a limited amount of sizes are now made. |
Drop In Locks with 3/4" backset, 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.
Install Considerations
- Use on doors hinged on right.
- Lock fits into cut out pocket in top-edge of drawer or side-edge off door. Once installed only brass selvedge and keyhole are exposed.
If replacing a lock: the backset measurement must be determined
- If you have original lock: measure distance between top edge of lock to lock pin in center of keyhole. This measurement is known as the backset.
- If old lock not available, determine backset by measuring: distance from center of keyhole (where lock pin would be) to top edge of drawer or side edge of door.
- The backset measurement of the replacement lock, must match backset measurement in original lock and/or keyhole location measurement in drawer or cabinet door.
