Half Mortise Box Lock Measurement Diagram

Economical Box Locks, with half mortise design, are used on chests and boxes with lift lids. Lock is mortised into interior of box front and strike attaches underneath lid. When closed, strike drops down into lock. 

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

Steel Half Mortise Box Lock, 1 inch Backset

The box lock finished my box very well, giving it a professional look. I am very pleased with it. I learned I needed to be careful with the key. One lock was too tight and I happen to break the key.
