Corbin Russwin CL3391 Grade 1 Keyed Lever & Turnpiece Extra Heavy-Duty Cylindrical Lever Lock

Corbin Russwin CL3391-KEYED Extra Heavy-Duty Cylindrical Lever Lock with Keyed Lever & Turnpiece Function

Grade 1 Commercial Cylindrical Lockset for High-Traffic Institutional and Commercial Applications

The Corbin Russwin CL3391 is an extra heavy-duty, Grade 1 cylindrical lever lock from the CL3300 Series, engineered for demanding commercial, industrial, and institutional environments. This keyed lever and turnpiece function lock features a deadlocking latchbolt operated by lever or turnpiece, except when the lever is locked by key — at which point the latchbolt is operated by key in the lever or by the turnpiece, with the lever handle freewheeling in the locked position. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CL3391 is built from steel with zinc dichromated corrosion-resistant construction and includes a conventional 6-pin cylinder with two nickel silver keys. The most common configuration features the NZD Newport lever in a 626 Satin Chrome finish.
