Sargent LC-8217 Lnl 26D Grade 1 Mortise Lock

Product Description

The SARGENT LC-8217 LNL 26D is a Grade 1 mortise lock designed for asylum and institution applications where security and durability are critical. It features an L-style lever trim and an LN rose, and ships in a field-reversible configuration so the same unit can be installed on either hand of the door without special ordering. The lock is supplied less cylinder, meaning the installer selects and provides the cylinder to match the facility keying system. The finish is satin chrome (26D), which resists wear in high-traffic institutional environments. This is a professional-grade lock body intended for demanding commercial and institutional settings.

This mortise lock is suited for residential psychiatric facilities, correctional institutions, hospitals, and similar high-security or controlled-access environments where a Grade 1 lock is required by specification or code. The less-cylinder configuration makes it adaptable to existing master-key systems. The ASA strike is included, allowing installation into standard ASA-prep door frames common in institutional construction. Field reversibility reduces inventory requirements and simplifies stock management for facilities maintenance teams.

Installation Notes
