Corbin Russwin CL3820 Privacy Cylindrical Lever Lock | Grade 2 | ANSI F76A | Non-Keyed

Standard-Duty Commercial Privacy Lock with Push-Button Locking and Emergency Release

The Corbin Russwin CL3820 is a standard-duty, non-keyed cylindrical lever lock engineered for commercial privacy applications in the CL3800 Series. Conforming to ANSI function F76A (Privacy Lock), this Grade 2 leverset 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. Designed for doors 1-3/8" to 1-3/4" thick with a 2-3/4" backset, the CL3820 delivers an outstanding combination of value and performance for standard commercial environments. The unit carries a UL-cUL 3-hour fire rating and ANSI/BHMA Grade 2 certification, making it a reliable choice wherever code-compliant privacy hardware is required.
