Sargent LC-10XG38 Ll 26D Classroom Cylindrical Lock

Product Description

The SARGENT LC-10XG38 LL 26D is a Grade 1 cylindrical lockset designed for classroom security and intruder control applications. It features an L lever handle with an L rose trim and ships less cylinder, meaning the installer supplies the cylinder to match the facility's keying system. The satin chrome finish (26D) provides a low-glare, corrosion-resistant surface suited to high-traffic institutional environments. Non-handed design simplifies inventory and installation by fitting both left- and right-hand doors without modification. Licensed locksmiths, commercial door hardware specialists, and facilities maintenance teams are the typical installers for this hardware.

This lockset is built for educational facilities requiring intruder lockdown capability at the classroom door. The classroom security function allows the door to be locked from the corridor side with a key, keeping occupants safely inside without requiring anyone to enter the hallway. It is appropriate for K-12 schools, university classrooms, and similar institutional occupancies where ANSI Grade 1 durability and security are required. The less-cylinder configuration supports integration into existing master key or interchangeable core systems already deployed in a facility.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with cylindrical lockset preparation and ANSI/BHMA standards. Verify door prep dimensions and backset before installation, and confirm the supplied cylinder is compatible with the lock chassis before final assembly. Follow all applicable building codes and ADA accessibility requirements for lever hardware installation height and clearance. De-latch and secure the door in the open position before beginning hardware removal or installation to prevent accidental lockout.
