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.
When replacing locks: Lock-backset must match keyhole-location in furniture. This is critical so that key can be inserted through door front into lock-keyhole. If these 2 measurements do-not match, it will not be possible to insert key through keyhole in door into lock.
