Sargent LC-8237 Lnp 26D Classroom Mortise Lock Satin Chrome

Product Description

The SARGENT LC-8237 LNP 26D is a Grade 1 classroom mortise lock designed for commercial door hardware applications requiring a high level of security and durability. It features a P-style lever handle paired with an LN rose and is field reversible, allowing installation on either left-hand or right-hand doors without special-order components. The lock ships less cylinder, meaning the installer supplies a compatible mortise cylinder separately. An ASA strike is included. The satin chrome (26D) finish suits institutional and commercial interiors where a clean, low-glare appearance is required.

This lock is intended for classroom security functions in commercial and institutional buildings, including K-12 schools, universities, and government facilities. The classroom function allows the door to be locked from the corridor side with a key while remaining free-egress from the interior at all times, meeting standard life-safety requirements for occupied educational spaces. Licensed locksmiths and commercial door hardware specialists are the primary installers of this product.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise lock prep and ANSI door standards. Confirm door handing before installation, though this unit is field reversible. A compatible mortise cylinder must be sourced and installed separately - do not operate the lock without the cylinder in place. Verify that the door frame is prepped to accept the included ASA strike and that the door thickness is compatible with the selected trim before beginning work.
