Sargent 8225 Lnl 26D Mortise Lock Satin Chrome

Product Description

The SARGENT 8225 LNL 26D is a Grade 1 mortise lock designed for dormitory and exit applications. It features an L-series lever trim paired with an LN rose, giving it a clean, low-profile appearance suited to institutional and commercial door hardware installations. The lock is field reversible, meaning it can be configured for either hand without returning the hardware to the factory. A conventional cylinder format and included ASA strike make this unit compatible with standard door prep and frame conditions. Licensed locksmiths, door hardware specialists, and commercial contractors are the typical installers.

This mortise lock is intended for commercial and institutional environments where Grade 1 security and durability are required. Dormitory-function locksets allow free egress from the inside at all times while restricting entry from the outside, making them well suited for residential hall corridors, apartment entries, and similar occupancies. The satin chrome (26D) finish provides a consistent aesthetic in environments where corrosion resistance and a matte metallic appearance are preferred. Field reversibility reduces stocking requirements and simplifies installation across mixed-hand door sets.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise lock pocket preparation and ANSI/BHMA standards. Verify door thickness, hand, and backset before installation, and confirm the door frame accepts an ASA strike. Disconnect any access control wiring or power to electrified hardware before servicing adjacent components. Follow the manufacturer's template for mortise pocket dimensions to avoid door edge damage.
