Sargent LC-8237 Lnl 10B Classroom Mortise Lock

Product Description

The SARGENT LC-8237 LNL 10B is a Grade 1 classroom mortise lock designed for institutional and commercial door hardware applications. It features an L-series lever trim paired with an LN rose, and ships field reversible for flexible handing on site. The lock is supplied less cylinder, allowing the installer to fit the specified core or cylinder to match the building keying system. Finished in Dark Oxidized Satin Bronze Oil Rubbed (10B), it suits door hardware schedules that call for an oil-rubbed bronze aesthetic with the durability of a Grade 1 mortise body.

This lock is intended for classroom and institutional applications where a lockable function from the corridor side is required while allowing free egress from the interior. Typical installations include K-12 schools, universities, healthcare facilities, and government buildings. The field-reversible design reduces the need for separate stock for left-hand and right-hand doors, and the included ASA strike is compatible with standard door frame preparations.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware installer familiar with commercial mortise lock prep and ANSI-standard door preparations. Verify door hand and backset before mortising. Cylinder installation should follow the cylinder manufacturer's specifications and local keying authority requirements. Ensure the door and frame are properly aligned before final trim attachment to prevent binding.
