Corbin Russwin CL3393 Grade 1 Service Station Extra Heavy-Duty Cylindrical Lever Lock

Corbin Russwin CL3393-KEYED Service Station Extra Heavy-Duty Cylindrical Lever Lock with Deadlocking Latch

Grade 1 Commercial Cylindrical Lockset with ANSI F92 Service Station Function

The Corbin Russwin CL3393-KEYED is an extra heavy-duty, Grade 1 commercial cylindrical lever lock engineered for demanding service station applications under ANSI function F92. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this lockset features a throw-off latchbolt operated by lever and a slotted push button that activates a deadlocking latch when pushed in and turned, causing the outside lever to become freewheeling. The outside lever is unlocked by key or by rotating the inside lever once the push button is returned to its original position. Constructed with steel and zinc dichromated components for corrosion resistance, the CL3393 is part of the proven CL3300 Series platform built for years of dependable operation in high-traffic commercial environments.
