Commercial-Grade Entrance/Office Security with ANSI/BHMA Grade 1 Certification

The Corbin Russwin CL3561-KEYED is a heavy-duty Grade 1 cylindrical lever lock engineered for demanding commercial, institutional, and multi-family applications. Designed to the ANSI function F82A (Entrance/Office), this keyed cylindrical lever lock features a deadlocking latchbolt operable 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. Compatible with door thicknesses of 1-3/8" to 1-3/4" and featuring a 2-3/4" backset, the CL3561 is part of the CL3500 Series and is constructed with a steel and zinc dichromated substrate for corrosion resistance.
