Corbin Russwin CL3851NZD626CL6 Grade 2 Lever Lockset

Product Description

The CORBIN RUSSWIN CL3851NZD626CL6 is a Grade 2 standard-duty cylindrical lever lockset designed for entrance, entry, and office door applications in commercial environments. Supplied in a 626 Satin Chrome finish, it ships less core - meaning the cylinder core and keys are not included and must be sourced separately. The non-handed solid cast levers work on either door hand without modification, and independent return springs support the Lever Release design, which allows the outside lever to rotate freely when in the locked position to resist vandal-induced damage. Through-bolts secure the unit directly to the door for a solid, stable mount. The lockset carries an ANSI/BHMA A156.2 Series 4000 Grade 2 certification and a UL 3-hour fire rating.

This lockset is suited for standard commercial and light institutional applications where Grade 2 performance is appropriate. Typical installations include interior offices, closets, multi-family housing corridors, restaurants, and retail complexes. It is intended for use as an economical complement to the CL3300 Series Extra Heavy-Duty and CL3500 Series Heavy-Duty cylindrical lever locksets, allowing contractors and facility managers to reduce overall project hardware costs on doors that do not require heavy-duty ratings without sacrificing core function or durability. A licensed locksmith or commercial door hardware installer typically handles specification and installation.

Compatibility

Designed as a Grade 2 cylindrical lever lockset for standard commercial door applications. Compatible with the CL3300 Series Extra Heavy-Duty and CL3500 Series Heavy-Duty Cylindrical Lever Locksets for mixed-grade project specifications. Requires a 2-3/4 inch backset door prep.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI door prep standards. Verify the door is prepared for a 2-3/4 inch backset before installation, and confirm the door assembly is rated to match the UL 3-hour fire rating if fire-door compliance is required. Because this unit ships less core, the cylinder core must be installed separately before the lockset is functional. Disengage all power-operated door hardware and confirm the door is secured open before beginning work.
