Marks USA 195RF LFIC Storeroom Clutched Lever Lockset — Grade 1 Survivor Series, Less Core, American Lever
The Marks USA 195RF is a Grade 1 Survivor Series LFIC (Large Format Interchangeable Core) Storeroom Clutched Lever Lockset engineered for demanding commercial environments where durability and long-term performance are paramount. Built on a cylindrical lock chassis with cast retractors on bronze roller bearings, this lockset features a unique stainless steel clutch mechanism that disengages the levers from the retractor and interior mechanisms when locked — allowing the levers to swing freely without resistance, eliminating lever droop and dramatically reducing component wear. Rated for over 3.6 million cycles, it exceeds BHMA Grade 1 specifications by 300%, and carries a 3-Hour Fire Rating. Available backsets are 2-3/8" and 2-3/4", with door thickness compatibility of 1-5/8" to 1-7/8" (use K1904 spacer for 1-3/8" doors).
