Overview

About this product

Schlage part L283-138 is the lock body that sits inside the door pocket on L9456/57/96 mortise locks, covering the latch-and-deadbolt functions in that group. It is a common repair part on doors that pair a latch with a deadbolt, letting you keep the existing trim, cylinder and door prep while replacing the mechanism.

The case is rated Grade 1 with a 3-hour fire rating, and it carries a UL 10C/ULC-S104 listing. It ships as the case only, with no armor front, strike, screws or cylinder, and it is field reversible so the same part works on either hand of door.

What the function does

Replacement mortise lock case. For use with L9456/57/96. It holds the latch and bolt mechanism inside the door and is field reversible for left or right hand doors; trim, cylinder, armor front and strike are reused or bought separately.
