Dexter Commercial C1000CLRMR626SFIC Classroom Cylindrical Lock

Product Description

The DEXTER COMMERCIAL C1000CLRMR626SFIC is a Grade 1 classroom cylindrical lock built for commercial door applications. It features a regular trim style and a satin chrome (626) finish. The lock ships with a 1.125 inches by 2.75 inches backset and an ANSI 1.25 inches by 4.875 inches curved lip strike included. The core is a Special Function Interchangeable Core (SFIC) design that accepts 6-pin and 7-pin cylinders, giving facilities managers flexibility when rekeying or replacing cores across a master-key system. At 4.30 pounds, this is a solid, hardware-grade unit intended for licensed locksmiths and commercial door hardware installers.

This lock is suited for classroom and institutional door applications in commercial and light-industrial buildings. The classroom function keeps the latch locked from the outside by default, allowing exit at any time and entry only by key or from inside - a standard requirement in K-12 and higher-education facilities. The lock accommodates doors ranging from 1.375 inches to 2 inches in thickness, making it compatible with the vast majority of hollow-metal and solid-wood commercial doors. The SFIC prep accepts Schlage C keyways, including 6-pin cylinders keyed alike, keyed different, and SFIC configurations.
