Overview

About this product

The Sargent 8241 is an 8200 Line mortise lock in the classroom security intruder deadbolt function, fitted here with LNL lever trim. It is rated ANSI/BHMA Grade 1 and is built for 1-3/4 inch doors with a 2-3/4 inch backset. Because it is keyed on both sides, staff can throw the deadbolt from inside the room with a key, without stepping into the corridor.

The lockbody uses a one-piece anti-friction reversible latch with a 3/4 inch throw and an 8 inch by 1-1/4 inch face. The LNL trim has a 2 inch rose and a lever projection of 2-3/8 inch. Finish choices include 26D, 10B and 32D. It can be ordered with a conventional cylinder, prepped for a small format interchangeable core (SFIC), prepped for a large format interchangeable core (LFIC), or without a cylinder.

What the function does

Double cylinder lock with a deadbolt. A key from either side throws or retracts the deadbolt. With the deadbolt thrown, the first key turn retracts it and a second turn unlocks the outside lever. Retracting the latchbolt by key from either side also unlocks the outside lever. The outside lever retracts the latchbolt unless it is locked. With the deadbolt thrown, the inside lever retracts latchbolt and deadbolt together while the outside lever stays locked. Auxiliary deadlatch.
