Dexter Commercial C1000CLRMR626KDC Classroom Cylindrical Lock

Product Description

The DEXTER COMMERCIAL C1000CLRMR626KDC is a Grade 1 classroom-function cylindrical lock designed for commercial door hardware applications. It features a regular lever trim with a C keyway and a 2-3/4 inch backset. The face bore accepts a 1-1/8 inch face plate, and the unit ships with an ANSI-standard strike plate. The satin chrome (626) finish meets typical institutional and commercial aesthetic requirements. This lock is rated Grade 1 under ANSI/BHMA standards, making it appropriate for high-cycle commercial installations. It is installed by licensed locksmiths or commercial door hardware technicians on interior doors requiring classroom-function access control.

The C1000CLRMR626KDC is suited for classroom and institutional interiors where a lockable lever set with outside key control and always-free egress from the inside is required. Typical applications include K-12 schools, universities, and municipal or government office buildings. The clutching lever mechanism protects the internal lock components from forced rotation attempts, a standard requirement in educational facility specifications. Installation requires a standard cylindrical lock prep with a 2-1/8 inch cross bore and the specified 1-1/8 inch face bore.
