Marks 195ssrs/32d Classroom Lever Lockset Grade 1

Product Description

The MARKS 195ssrs/32d is a Grade 1 mechanical cylindrical lever lockset configured for classroom function, designed for installation in high-security and specialty commercial environments. Built on the 1SS19 lever style with a polished stainless steel finish, it features an interchangeable core (IC) cylinder with a 6-pin Marks C keyway and ships keyed alike with 2 keys. The lockset carries a 3-hour fire rating and meets BHMA and cULus standards. Its ligature-resistant construction makes it appropriate for behavioral health and detention facility applications. Installation is handled by licensed locksmiths or commercial door hardware technicians.

This lockset is rated for cylindrical door prep and fits doors 1-3/4 inches thick, with a maximum door thickness of 1-7/8 inches. The classroom function (ANSI F84) allows free egress from the inside at all times while the outside lever is locked by default and released by key. The 2-3/4-inch backset and ASA curved lip strike are standard commercial dimensions. The non-handed design simplifies ordering and installation across multiple door configurations. Intended for institutional settings including schools, behavioral health facilities, and detention environments where durability and ligature resistance are required.
