Sargent 70-8237 LW1L 26D Classroom Mortise Lock

Product Description

The SARGENT 70-8237 LW1L 26D is a classroom-function mortise lock configured with an LW1 escutcheon, L lever handle, and a Small Format Interchangeable Core (SFIC) prep that ships without a core installed. Designed for commercial door hardware applications, it provides the lever trim, lock body, and escutcheon in a single assembly ready to accept a compatible SFIC cylinder. The satin chrome (26D) finish gives it a clean, durable appearance suited to institutional and educational environments. Licensed locksmiths, door hardware specialists, and commercial contractors typically specify and install this type of hardware.

Classroom mortise locks are standard hardware in K-12 schools, universities, government buildings, and commercial office facilities where controlled access is required. The classroom function allows free egress from inside at all times while the exterior lever can be locked by key from outside without entering the room. The SFIC prep on this unit is designed for facilities that use a large-scale master key system with interchangeable cores, allowing cores to be swapped across doors without removing the lock body. The L lever and LW1 escutcheon combination provides a trim profile commonly specified in commercial architectural hardware schedules.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise lock prep specifications.

A compatible SFIC core must be sourced and installed separately to complete the lock assembly. Follow all applicable building codes and access-control requirements for the occupancy type.
