Corbin Russwin CL3110 Passage/Closet - Grade 1 Vandal Resistant Cylindrical Lever Lock

Corbin Russwin CL3110-NON-KEYED Passage/Closet Cylindrical Lever Lock Grade 1 Vandal Resistant with T-Zone Construction

Commercial-Grade Non-Keyed Cylindrical Leverset for High-Traffic Applications

The Corbin Russwin CL3110 is a non-keyed, Grade 1 cylindrical lever lock engineered for passage and closet applications (ANSI function F75) in demanding commercial environments. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this leverset features Corbin Russwin's patented T-Zone construction — interlocking the aligning and latch tubes to form a rugged torque-resistant "T" in the critical twist area — tested to over 15 million cycles, exceeding ANSI/BHMA Grade 1 standards by 15 times. Both levers are always free, allowing latchbolt retraction from either side without a key, making it ideal for offices, healthcare facilities, educational institutions, and other high-traffic commercial settings.
