Sargent LC-8237 Ll 26D Grade 1 Classroom Mortise Lock

Product Description

The SARGENT LC-8237 LL 26D is a Grade 1 classroom mortise lock designed for demanding commercial and institutional door hardware applications. It features an L-lever handle with an L-rose trim and ships in a Satin Chrome (26D) finish. The lock is field reversible, allowing handing adjustment on the job without returning to the shop. It ships less cylinder, meaning the installer must supply a compatible mortise cylinder separately. Licensed locksmiths and commercial door hardware installers are the primary trades for this product.

This mortise lock is built for classroom security functions, where the outside lever locks or unlocks by key while the inside lever remains free-turning for egress at all times. That function makes it well-suited for K-12 schools, universities, and similar institutional facilities where controlled access and life-safety egress requirements must both be met. The ASA strike is included for straightforward frame preparation on standard hollow metal and wood door frames.

Key Features

• Grade 1 heavy-duty rating for high-cycle commercial and institutional use
• Classroom security function locks outside lever by key while maintaining free inside egress
• Field reversible handing for flexible installation on left-hand or right-hand swing doors
• Less cylinder configuration allows the installer to specify a compatible mortise cylinder separately
• ASA strike included for compatibility with standard door frame preps
• Satin Chrome (26D) finish for corrosion resistance and institutional aesthetics

Compatibility

Designed as an OEM-style mortise lock for commercial and institutional doors requiring a Grade 1 classroom security function with standard mortise pocket preparation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware installer familiar with mortise lock pocket preparation and ANSI/BHMA standards. Verify door thickness and backset before installation, and confirm the mortise pocket dimensions match the lock body. Because the unit ships less cylinder, a compatible mortise cylinder must be sourced and installed separately before the lock is operational. Always follow applicable building and fire codes, including IBC egress requirements, when installing classroom security hardware.
