Corbin Russwin CL3175 Corridor/Dormitory Grade 1 Vandal Resistance Cylindrical Lever Lock

Corbin Russwin CL3175-KEYED Corridor/Dormitory Grade 1 Cylindrical Lever Lock with Vandal Resistance and T-Zone Construction

Patented Grade 1 Cylindrical Lever Lock Engineered for High-Traffic Commercial Applications

The Corbin Russwin CL3175-KEYED is a patented Grade 1 cylindrical lever lock from the CL3100 Series, designed for Corridor/Dormitory (ANSI function F90) applications in demanding commercial, institutional, and industrial environments. This keyed cylindrical lever lock accommodates door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, and features a conventional 6-pin cylinder with two nickel silver keys included. Built with Corbin Russwin's proprietary T-Zone construction, the CL3175-KEYED interlocks the aligning and latch tubes to form a rugged torque-resistant "T" in the critical twist area, providing strength and durability that far exceeds ANSI/BHMA A156.2 Series 4000 Grade 1 standards. The lock body is manufactured from steel with zinc dichromate treatment for corrosion resistance, and is non-handed for simplified installation.
