Corbin Russwin CLX3357-NZD-613E-CT6D-LFIC Storeroom Lever Lock

Product Description

The CORBIN RUSSWIN CLX3357-NZD-613E-CT6D-LFIC is a Grade 1 storeroom cylindrical lever lock from the CLX3300 Series, engineered for high-traffic commercial and institutional applications where security and finish durability matter. It features a Newport lever design, a 2-3/4 inch backset, and ships with an ANSI SA114 strike. The lock is prepped for Corbin Large Format Interchangeable Core (LFIC) with a 6-pin configuration and includes a disposable plastic core in place of the permanent LFIC. Finished in 613E Dark Oxidized Satin Bronze (US10BE), it meets ANSI/BHMA Grade 1 requirements for strength and cycle life. Licensed locksmiths, security contractors, and commercial door hardware installers are the primary installers of this hardware.

The CLX3357-NZD-613E-CT6D-LFIC is suited for storeroom function applications in commercial buildings, institutional facilities, schools, healthcare environments, and similar high-traffic installations. In storeroom function, the outside lever is always locked and requires a key or credential to retract the latch, while the inside lever remains free-egress at all times. The Newport lever profile and 613E Dark Oxidized Satin Bronze finish make it appropriate for projects where a consistent, refined aesthetic is required alongside Grade 1 security performance. It is designed for both new construction and retrofit door hardware projects.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with cylindrical lock prep requirements and ANSI/BHMA standards.
