Corbin Russwin CL3180 Passage & Blank Plate Grade 1 Vandal Resistance Cylindrical Lever Lock

Corbin Russwin CL3180 Passage & Blank Plate Grade 1 Cylindrical Lever Lock with T-Zone Vandal Resistance, Non-Keyed

Commercial-Grade Communicating Passage Lockset with Patented T-Zone Construction

The Corbin Russwin CL3180 is a non-keyed, ANSI function F111 Passage & Blank Plate cylindrical lever lock engineered for single or double communicating doors in demanding commercial environments. Featuring a lever on one side and a blank plate on the other with levers always free, this Grade 1 lockset is built on the patented CL3100 Series platform with T-Zone construction that interlocks the aligning and latch tubes to form a rugged torque-resistant "T" in the critical twist area. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CL3180 delivers strength and durability far exceeding ANSI/BHMA A156.2 Series 4000 Grade 1 standards. The lockset substrate is steel with zinc dichromate treatment for corrosion resistance, and it is available in 11 architectural finishes including the most common configuration of NZD Newport lever in 626 Satin Chrome finish.
