Marks USA 195RDA Vestibule Clutched Lever Lockset — Grade 1, Small Format IC, 3-Hour Fire Rated
The Marks USA 195RDA is a commercial-grade Vestibule Clutched Lever Lockset from the 195 Series, engineered with a unique stainless steel clutch mechanism that disengages the levers from the retractor when locked — allowing them to swing freely without resistance, eliminating lever droop and dramatically reducing wear on internal components. Built on a cylindrical lock chassis with cast retractors on bronze roller bearings, this lockset exceeds BHMA Grade 1 specifications by 300%, achieving over 3.6 million cycles. It supports 2-3/8" and 2-3/4" backsets, accommodates door thicknesses of 1-5/8" to 1-7/8" (with optional K1904 spacer for 1-3/8" doors), and carries a 3-Hour Fire Rating along with ANSI/BHMA and UL Listed certifications.
