Sargent 10XG37 Lb 26D Classroom Cylindrical Lock

Product Description

The SARGENT 10XG37 LB 26D is a Grade 1 classroom cylindrical lock designed for educational and institutional door hardware applications. It features a B lever handle paired with an L rose, a conventional cylinder, and a satin chrome (26D) finish. Grade 1 is the highest ANSI/BHMA performance rating for cylindrical locks, indicating heavy-duty cycle testing and load resistance suited to high-traffic environments. This lock is non-handed, meaning it installs on doors with either a left-hand or right-hand swing without modification. Licensed locksmiths, door hardware installers, and commercial contractors are the typical trades installing this hardware.

The 10XG37 LB 26D is intended for classroom security applications in K-12 schools, universities, and other institutional facilities. The classroom function allows the lever on the outside to be locked or unlocked by key without disturbing the inside lever, which remains free-turning at all times for egress compliance. This configuration supports life-safety code requirements for occupied rooms. The conventional cylinder accepts standard key blanks common to institutional master-key systems.

Installation Notes

Installation is typically performed by a licensed locksmith or commercial door hardware technician familiar with ANSI cylindrical lock prep standards. Verify the door prep (bore diameter, cross-bore, and backset) matches the lock specifications before installation. Ensure the door is not under load or latched during installation to avoid damage to the latch mechanism. Consult local building and fire codes, including IBC egress requirements, to confirm the classroom function is appropriate for the intended occupancy.
