Sargent 8225 Lnj 26D Mortise Lock Satin Chrome

Product Description

The SARGENT 8225 LNJ 26D is a Grade 1 mortise lock designed for dormitory and exit door applications. It combines a J-style lever handle with an LN rose trim and accepts a conventional cylinder, making it a reliable choice for institutional and commercial door hardware installations. The satin chrome (26D) finish provides a clean, low-glare appearance suited to high-traffic corridors. This lock is field reversible, allowing installation on left- or right-hand swing doors without returning to a supplier for a handed unit. Installation is typically performed by a licensed locksmith or commercial door hardware technician.

This mortise lock is appropriate for dormitory-function applications where the outside lever can be locked or unlocked by key, while the inside lever remains free-egress at all times. It is also suited for exit door configurations in commercial and institutional buildings such as schools, universities, hospitals, and office facilities. The ASA strike is included, allowing direct installation into standard mortise door prep cutouts. The J lever style and LN rose are factory-mounted and ship ready for installation.

Installation Notes

Mortise lock installation should be performed by a qualified locksmith or commercial door hardware technician familiar with local building and fire code requirements. Power down or de-energize any electrified door hardware in the opening before beginning service. Verify door thickness, backset, and handing before installation, and confirm the door prep matches the mortise case dimensions. Consult applicable codes, including IBC and NFPA 80 where fire-rated assemblies are involved, to ensure the installed function and trim meet egress requirements.
