Corbin Russwin CL3359-KEYED Storeroom/Public Restroom Extra Heavy-Duty Cylindrical Lever Lock with Lever Release Vandal Resistance

Grade 1 Extra Heavy-Duty Cylindrical Lockset for Commercial Storeroom and Public Restroom Applications

The Corbin Russwin CL3359-KEYED is a Grade 1 extra heavy-duty cylindrical lever lock engineered for storeroom and public restroom functions in demanding commercial, industrial, and institutional environments. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this lockset features a deadlocking latchbolt operated by the inside lever, while the outside lever is unlocked by key and retains the key in unlock mode. When the key is removed, the outside lever returns to the locked position with a freewheeling lever handle, ensuring controlled access at all times. The inside lever remains always free for unrestricted egress. Built on the proven CL3300 Series platform, this lock is manufactured with high-quality steel and zinc dichromated components for corrosion resistance and years of dependable operation.
