Corbin Russwin CLX3351-NZD-626-L4 Grade 1 Cylindrical Lock

Product Description

The CORBIN RUSSWIN CLX3351-NZD-626-L4 is a Grade 1 entrance cylindrical lock featuring the Newport lever style in a satin chrome (626) finish. Built for high-traffic commercial doors, it meets ANSI/BHMA Grade 1 standards and exceeds rigorous abuse testing — withstanding over 3,100 inch-pounds of torque and 1,600 pounds of offset lever pull. The lock body accepts all standard cylinder formats, and the non-handed design works on any door swing. A 2-3/4 inch backset and adjustable push/turn button accommodate a range of door thicknesses. Licensed locksmiths, door hardware installers, and commercial general contractors typically handle this product.

This lock is suited for commercial and institutional environments where security, durability, and code compliance are required — office buildings, healthcare facilities, schools, and other high-use applications. The L4 designation indicates a 6-pin cylinder configuration. The satin chrome finish provides a neutral aesthetic that integrates with a wide range of commercial door hardware standards. The non-handed body simplifies stocking and field installation, reducing the chance of ordering errors on large projects.

Confirm door prep dimensions — bore diameter, cross-bore spacing, and backset — match the lock specifications before installation. Ensure the door is held open or properly blocked and that access control power is disconnected before servicing any integrated hardware.
