Sargent 70-8237 Lnj 32D Classroom Mortise Lock Satin Ss

Product Description

The SARGENT 70-8237 LNJ 32D is a classroom mortise lock configured with an LN rose, J lever, and a Small Format Interchangeable Core (SFIC) prep that ships without the core installed. Finished in satin stainless steel (32D), this lock is built for institutional door applications where security, durability, and key control matter. Mortise locks of this configuration are installed by licensed locksmiths or commercial door hardware specialists. The SFIC prep allows facilities teams to standardize on a single key platform across multiple openings without rekeying individual cylinders.

This lock is suited for commercial and institutional settings such as schools, universities, healthcare facilities, and government buildings. The classroom function is designed so the lever on the outside can be locked or unlocked by key without disturbing the inside lever, which always allows free egress. The J lever profile and LN rose are typical of commercial door hardware specifications written by architects and facility managers following ANSI and BHMA guidelines.

Key Features

• Classroom mortise lock function allows outside lever lockout while maintaining free egress from inside
• SFIC prep accepts Small Format Interchangeable Cores for simplified rekeying and key control programs
• Ships less core, allowing the installer to specify and insert the preferred SFIC cylinder separately
• J lever design on LN rose provides a clean, institutional profile suited for high-traffic commercial doors
• Satin stainless steel (32D) finish offers corrosion resistance and a consistent appearance over time

Compatibility

Designed as an OEM-style mortise lock for commercial and institutional doors requiring a classroom function with SFIC prep hardware. No specific compatible model numbers or system families were provided in the product data.

Installation Notes

Mortise locks are installed by licensed locksmiths or qualified commercial door hardware technicians familiar with ANSI A156.13 mortise lock standards. The door must be properly prepped with a mortise pocket, strike cutout, and rose bore to accept this lock body. Always verify door thickness, backset, and handing before installation. The core must be sourced and installed separately; do not operate the lock in a security application without a properly seated SFIC cylinder.
