Sargent 70-10XG37 Lp 26D Classroom Cylindrical Lock

Product Description

The SARGENT 70-10XG37 LP 26D is a Grade 1 classroom cylindrical lock designed for institutional and commercial door hardware applications. It features a P lever handle and an L rose, finished in satin chrome (26D). The lock is factory-fitted with a Small Format Interchangeable Core (SFIC) disposable construction core, allowing temporary keying during the construction phase before the permanent SFIC core is installed. Non-handed design means it mounts on doors with either a left-hand or right-hand swing without modification. Grade 1 certification indicates heavy-duty cycle and force ratings appropriate for high-traffic commercial and institutional environments.

This lock is suited for classroom door applications in schools, universities, and institutional facilities where a classroom function is required - locking the exterior lever from the outside while the interior lever remains free for egress. The SFIC core format is commonly specified on campuses and facilities using Best, Falcon, or other compatible SFIC key systems. Installation is typically performed by licensed locksmiths or commercial door hardware technicians as part of new construction or renovation projects.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician. Verify door prep dimensions - bore diameter and cross-bore spacing - before installation to confirm compatibility with the existing or new door. Remove the disposable construction core and install the permanent SFIC core before the facility is occupied. Confirm that the installed function complies with applicable building codes and life-safety egress requirements for the room type.
