Corbin Russwin CL3361 Grade 1 Entrance/Office Extra Heavy-Duty Cylindrical Lever Lock

Corbin Russwin CL3361-KEYED Entrance/Office Extra Heavy-Duty Cylindrical Lever Lock with Vandal-Resistant Lever Release Design

Grade 1 Commercial Cylindrical Lockset for High-Traffic Entrance and Office Applications

The Corbin Russwin CL3361-KEYED is an extra heavy-duty, Grade 1 commercial cylindrical lever lock engineered for demanding entrance and office applications. Conforming to ANSI function F82A, this keyed cylindrical lever lock features a deadlocking latchbolt operated by lever from either side, except when the push button locks the outside lever. The push button is released by turning the inside lever or by key in the outside lever, and closing the door does not release the push button, ensuring the inside lever remains always free. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CL3361 is constructed from steel with zinc dichromate treatment for corrosion resistance, and is available in all standard architectural finishes including the most common configuration of NZD Newport lever in 626 Satin Chrome finish.
