Sargent 10XG37 Lb 26 Classroom Cylindrical Lock

Product Description

The SARGENT 10XG37 LB 26 is a Grade 1 classroom cylindrical lock designed for institutional and commercial door hardware applications. It features a B lever handle paired with an L rose trim and a conventional cylinder for keyed entry control. The bright chrome finish provides a clean, durable appearance suited to high-traffic environments. Non-handed design simplifies inventory and installation, as the lock works on doors of either hand without special ordering. Licensed locksmiths, commercial door hardware installers, and facility maintenance technicians are the primary trades that specify and install this unit.

This lock is engineered for classroom and institutional use where outside-key lockdown capability is standard practice. The Grade 1 rating indicates heavy-duty commercial performance, making it appropriate for K-12 schools, universities, government buildings, and similar facilities that require reliable access control. The conventional cylinder format accepts standard keyways common in commercial master-key systems, allowing straightforward integration into existing keying schedules.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI cylindrical lock prep standards. Verify the door bore preparation matches the cylindrical lock chassis diameter and backset before installation. Confirm the door frame strike is aligned and properly reinforced for Grade 1 hardware. Always test lockdown function and free-egress operation after installation to confirm correct operation before returning the door to service.
