Marks USA 195SSRF Storeroom Anti-Ligature Clutched Lever Lockset, Small Format IC, Less Core

The Marks USA 195SSRF is a commercial-grade storeroom anti-ligature cylindrical lever lockset engineered for demanding environments where durability, safety, and long-term performance are critical.

Designed for Small Format Interchangeable Core (SFIC) applications and sold less core, it accommodates door thicknesses of 1-5/8" to 1-7/8" (with optional K1904 spacer for 1-3/8" doors) and supports both 2-3/8" and 2-3/4" backsets. The 195SSRF carries a 3-Hour Fire Rating and is backed by the Marks Lifetime Mechanical Warranty.
