Overview
About this product
Sargent's 8243 apartment corridor mortise lock comes from the 8200 Line, here with the LNP lever design. One turn of the inside lever pulls back both bolts, so getting out does not take two steps. It meets ANSI/BHMA Grade 1 and is sized for 1-3/4 inch doors with a 2-3/4 inch backset.
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 LNP trim has a 2 inch rose and a lever projection of 2-1/2 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
Both the outside key and the inside thumbturn throw and retract the deadbolt. The outside lever is locked either by the toggle or by throwing the deadbolt, and it is unlocked only by the toggle. The key retracts the latchbolt and deadbolt while the outside lever stays locked. The inside lever always retracts latchbolt and deadbolt together, with the outside lever remaining locked. Auxiliary deadlatch.
