Sargent 70-10XG37 Ll 26D Classroom Cylindrical Lock

Product Description

The SARGENT 70-10XG37 LL 26D is a Grade 1 classroom cylindrical lock designed for institutional and commercial door hardware applications. It features an L lever handle on an L rose trim and ships with a disposable construction core that accepts Small Format Interchangeable Core (SFIC) cylinders. The satin chrome (26D) finish provides a low-glare, corrosion-resistant surface suited for high-traffic corridors and classroom entry points. The non-handed design installs on doors of either hand without modification, reducing stocking requirements for facilities and contractors.

This lock is intended for classroom security functions in K-12 schools, universities, government buildings, and other institutional facilities. The classroom function keeps the outside lever locked at all times and can be unlocked by key from the outside, meeting the access control workflow required in most educational occupancies. The SFIC disposable construction core allows the building to remain accessible during construction, then be rekeyed to the permanent master key system upon project completion without replacing the lock body.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician in accordance with the door manufacturer's preparation specifications and applicable building codes. Verify the door prep matches the cylindrical lock backset and cross-bore dimensions before installation. The construction core must be removed and replaced with the permanent SFIC cylinder before the facility is occupied. Always confirm the egress function operates freely before closing out the installation.
