Sargent 28LC-7G37 Ll 10 Classroom Cylindrical Lock

Product Description

The SARGENT 28LC-7G37 LL 10 is a Grade 2 classroom cylindrical lock designed for commercial door hardware applications in educational and institutional settings. This lock features an L lever handle and ships without a cylinder installed, allowing the installer to field-fit a compatible cylinder to match the existing keying system on site. The satin bronze finish provides a durable, low-sheen appearance suited to high-traffic interior doors. Non-handed design simplifies inventory and installation by fitting doors of either swing direction without modification.

This lock is intended for classroom door applications where the outside lever can be locked from the corridor side without a key, keeping the inside lever always free for egress. That function meets the access control requirements common in K-12 schools and institutional facilities. Licensed locksmiths, commercial door hardware installers, and general contractors working under commercial building permits typically handle this type of installation. The less-cylinder configuration makes it compatible with facility-wide master key systems when a matching cylinder is sourced separately.

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 and cross-bore dimensions match the lock specifications before installation. A compatible cylinder must be sourced and installed separately to complete the locking function. Confirm local building and fire codes for egress hardware requirements before final installation.
