Corbin Russwin CLX3381 Grade 1 Keyed Lever & Blank Plate - Cylindrical Lever Lock

Corbin Russwin CLX3381-KEYED Cylindrical Lever Lock - Keyed Lever & Blank Plate, ANSI F113, Grade 1

ANSI/BHMA Grade 1 Cylindrical Lock with Freewheeling Lever Release and 20 Million Cycle Verification

The Corbin Russwin CLX3381-KEYED is a commercial-grade cylindrical lever lock from the CLX3300 Series, engineered to ANSI/BHMA Grade 1 standards for high-traffic interior and exterior door applications. Configured to ANSI function F113, this lock features a keyed lever on one side and a blank plate on the other, with a deadlocking latchbolt that is controlled by the lever except when locked by key — at which point the lever handle freewheels for vandal resistance. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CLX3381-KEYED is manufactured from steel with zinc dichromate treatment for corrosion resistance, and supports a conventional 6-pin cylinder with L4 keyway. The most common configuration features the NZD Newport lever in 626 Satin Chrome finish.
