Steel Half Mortise Box Lock, 1 inch Backset

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.

Lock Size

• If replacing an old lock, BACKSET SIZE is critical, as keyhole in lock and furniture must line up together.
• Backset- Distance To Pin: 1"
• Lock Plate: 2-5/8" wide x 1-9/16" high
• Selvedge: 2-5/8" x 1/2"
• Key Size: Barrel: 3/16" D x 1-1/2", 2-3/16" Overall Length, Key-bit Height: 1/2"

Finding an exact match for an old lock is not always possible, as only a limited amount of sizes are now made.

Keyhole Covers

• Keyhole-covers not-included as furniture style dictates keyhole-cover design
• Insert Escutcheon#0242, #0237 or #0253 can be used with this lock

This full mortise lock is steel with a steel strike. It is very reasonably priced, as such: locking mechanism is average, not as smooth as finer made in European countries, yet is serviceable. Made in Asia.
