Corbin Russwin CL3320 Grade 1 Privacy Extra Heavy-Duty Cylindrical Lever Lock

Corbin Russwin CL3320-NON-KEYED Privacy Cylindrical Lever Lock | Extra Heavy-Duty Grade 1 | ANSI F76A

Commercial-Grade Privacy Security for High-Traffic Institutional and Commercial Applications

The Corbin Russwin CL3320 is an extra heavy-duty, non-keyed cylindrical lever lock engineered to ANSI function F76A (Privacy Lock) for demanding commercial, industrial, and institutional environments. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this Grade 1 lockset delivers the strength, quiet operation, and long-term dependability required in high-use facilities. The CL3320 features a throw-off latchbolt by lever, with the outside lever locked by push button — freewheeling in the locked position — and unlocked by an emergency release tool from outside, by rotating the inside lever, or by closing the door. The inside lever remains always free, ensuring reliable egress at all times. Constructed from steel with zinc dichromated corrosion resistance, the CL3320 is fire rated and non-handed for versatile installation.
