Overview
About this product
The Sargent 8237 is an 8200 Line mortise lock in the classroom function, fitted here with LNB 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. Classroom function lets a teacher or staff member lock the outside lever with a key while people inside can always get out.
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 LNB trim has a 2 inch rose and a lever projection of 2-5/8 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
A key on the outside retracts the latchbolt and also locks or unlocks the outside lever. The inside lever always retracts the latchbolt, so the door can be opened from inside whether or not the outside is locked. An auxiliary deadlatch is included.
