Sargent 28LC-10G37 Ll 26D Classroom Cylindrical Lock

Product Description

The SARGENT 28LC-10G37 LL 26D is a Grade 1 classroom cylindrical lock designed for institutional and commercial door applications. It features an L lever handle and ships less cylinder, meaning the lock core is not included and must be specified or sourced separately. The satin chrome (26D) finish provides a low-sheen, corrosion-resistant surface suited to high-traffic environments. This is a not-handed design, making it compatible with doors swinging in either direction without modification. Grade 1 is the highest ANSI/BHMA performance rating for cylindrical locks, appropriate for heavy-use commercial and institutional settings.

This lock is intended for classroom doors in schools, universities, government buildings, and similar institutional facilities where a keyed lockset with a lever trim is required. The classroom function typically allows the lever to remain unlocked from inside at all times while the exterior is controlled by key. The less-cylinder configuration is common in projects where a facility manager or locksmith supplies a specified key system or interchangeable core separately.

Key Features

• ANSI/BHMA Grade 1 rated for heavy-duty commercial and institutional use
• Classroom lockset function - interior lever always free, exterior controlled by key
• L lever handle design for ADA-compatible lever trim
• Less cylinder - lock body ships without a key cylinder, allowing field-specified core selection
• Not-handed - installs on left-hand or right-hand swing doors without adjustment
• Satin chrome (26D) finish for durability and low-reflectance aesthetics

Compatibility

Designed as an OEM-style cylindrical lock for commercial and institutional classroom door applications requiring a Grade 1 cylindrical chassis with L lever trim and a separately supplied cylinder or interchangeable core.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware professional. Verify the door prep (bore diameter and backset) matches the lock specifications before installation. Because this unit ships less cylinder, the appropriate key cylinder or interchangeable core must be installed before the lock is placed into service. Follow local building codes and ADA lever-height requirements when mounting hardware.
