Corbin Russwin CLX3372 Grade 1 Apartment Exit/Public Toilet - Cylindrical Lever Lock

Corbin Russwin CLX3372-KEYED Apartment Exit/Public Toilet Cylindrical Lever Lock ANSI F88 Grade 1, 1-3/4" to 2" Doors

Commercial-Grade Cylindrical Lever Lock for Apartment Exit and Public Toilet Applications

The Corbin Russwin CLX3372-KEYED is a heavy-duty, ANSI/BHMA Grade 1 cylindrical lever lock engineered for Apartment Exit and Public Toilet applications (ANSI function F88). Designed for doors ranging from 1-3/4" to 2" in thickness with a 2-3/4" backset, this keyed cylindrical lock features a deadlocking latchbolt operable by lever from either side, except when the key inside locks the outside lever — at which point the outside lever freewheels for vandal resistance. Manufactured from steel with zinc dichromate treatment for corrosion resistance, the CLX3372-KEYED is part of the CLX3300 Series, which has been UL cycle-tested to 20 Million Cycles (Verification ID: V875753) and carries a 7 Year Limited warranty, making it an ideal solution for high-traffic commercial and institutional openings.
