Marks USA 195SSL Grade 1 Anti-Ligature Clutched Lever Lockset — Privacy, 3-Hour Fire Rated

The Marks USA 195SSL is a Grade 1 Privacy Anti-Ligature Clutched Lever Lockset engineered for demanding commercial environments where durability, safety, and long-term performance are essential. Built on the Survivor leverset platform, this cylindrical lockset features a unique stainless steel clutch mechanism and bronze roller bearings that allow levers to swing freely when locked, eliminating lever droop and dramatically reducing wear on internal components. Rated for over 3.6 million cycles — exceeding BHMA Grade 1 specifications by 300% — and carrying a 3-Hour Fire Rating, the 195SSL is designed for doors with a thickness of 1-5/8" to 1-7/8" and supports both 2-3/8" and 2-3/4" backsets.
