Sargent 70-8237 Lnj 26D Classroom Mortise Lock Satin Chrome

Product Description

The SARGENT 70-8237 LNJ 26D is a classroom mortise lock configured with an LN rose, J lever, and a Small Format Interchangeable Core (SFIC) prep that ships less core. Mortise locks are the standard hardware choice in institutional and commercial door applications where durability, security, and code compliance are required. The satin chrome (26D) finish provides corrosion resistance suited to high-traffic corridors. This lock is installed by licensed locksmiths or commercial door hardware technicians as part of a complete door prep and hardware schedule.

This lock is designed for classroom-function applications, meaning the lever is typically locked from the outside at all times and can be released by a key, while remaining free-egress from the inside. That function is required in many K-12 and higher-education facilities. The SFIC prep allows the facility to install a Small Format Interchangeable Core from a compatible keying system at time of installation, enabling integration into an existing master key or access control program.

Key Features

• Classroom function lock keeps outside lever locked for controlled access while allowing free egress from inside
• SFIC prep accepts Small Format Interchangeable Cores - ships less core for owner-supplied keying
• LN rose and J lever provide a low-profile institutional trim profile
• Satin chrome (26D) finish suited for high-traffic commercial and institutional environments
• Mortise body construction for long service life in heavy-use door applications

Compatibility

Designed as an OEM-style mortise lock for commercial and institutional doors prepped to accept a standard mortise lock pocket with SFIC core preparation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise lock prep standards. Verify door thickness and backset before installation, and confirm the door is prepped to the correct mortise pocket dimensions. The core is not included and must be sourced separately to match the facility keying system. Follow applicable building and life-safety codes governing egress hardware, including NFPA 80 for fire-rated assemblies where applicable.
