Product Description
The Sargent 8239-LNA-10-RH is a 8200 Series Classroom Security Intruder Deadbolt mortise lock in Satin Bronze (US10/612). A key from either side — outside or inside — projects or retracts a 1-inch throw deadbolt, and projecting that deadbolt is the only thing that locks the outside lever. Sargent’s published function text states: “Trim inside retracts both latchbolt and deadbolt simultaneously, and unlocks outside trim.” ANSI F33 (per Sargent’s published catalog).
Includes a standard conventional mortise cylinder (keyed). Need it without a cylinder? Order the LC- less-cylinder variant of this part instead.

Pro-Tip from Our Locksmiths: When retrofitting from an older Sargent mortise lock, the 8200 drops right into the same prep — same backset, same strike. Save your customer the cost of new door prep.
