Schlage Commercial B663R626 Grade 1 Classroom Deadbolt

Product Description

The SCHLAGE COMMERCIAL B663R626 is a Grade 1 classroom deadbolt designed for commercial and institutional door applications. It features a Large Format Interchangeable Core (LFIC) with a C keyway, bitted to a 1-bitted configuration, which allows facilities with keying systems to swap cores without removing the lock body. The unit ships with a 12296 latch and a 10094 strike and carries a Satin Chrome (626) finish. Grade 1 classification meets the highest commercial duty rating under ANSI standards, making this deadbolt appropriate for high-traffic openings in schools, offices, and institutional facilities.

This deadbolt is suited for commercial and institutional environments where classroom-function security is required. The classroom configuration allows the outside lever or cylinder to be locked and unlocked from the inside without a key, a common requirement in school and healthcare settings. The Large Format Interchangeable Core design integrates into facilities already running LFIC keying systems, simplifying rekeying and core rotation across a master key system. Licensed locksmiths and commercial door hardware installers are the primary trades for this type of hardware.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI Grade 1 deadbolt installation procedures. Ensure the door and frame are properly reinforced to accept a commercial deadbolt and strike before installation. Power is not required for this mechanical lock, but verify that the door prep dimensions match the hardware before cutting or modifying the door. Core insertion and removal require a control key specific to the LFIC system in use.
