Marks USA 195DC Communicating Clutched Lever Lockset — Grade 1, Marks C Keyway, UL Listed 3-Hour Fire Rated
The Marks USA 195DC is a Grade 1 Communicating Clutched Lever Lockset from the 195 Series, engineered for demanding commercial applications where durability and security are paramount. Featuring "The Clutch" mechanism, the outside lever disengages when locked — turning freely without actuating the latch — dramatically reducing torque stress compared to rigid-lever locksets. The lockset withstands torque of 1,800 inch-pounds (over twice the ANSI/BHMA 1996 test value) and has been life tested to over 6 million cycles. Supplied with a 6-pin cylinder in Marks C keyway with 2 nickel-silver keys, it supports door thicknesses of 1-5/8" to 1-7/8" (use K1704 spacer for 1-3/8" doors) and is UL Listed with a 3-hour fire rating.
Key Features
- Clutch Mechanism — "The Clutch": When locked, the outside lever disengages and turns freely without opening the latch, reducing torque on the lever and preventing the failures common to rigid-lever locksets.
- Exceptional Torque Resistance: Withstands 1,800 inch-pounds of torque — over twice the ANSI/BHMA (1996) test value — for superior resistance to forced entry and abuse.
- Heavy-Duty Life Cycle Rating: Life tested to over 6 million cycles and fully operational after testing, ensuring long-term reliability in high-traffic commercial environments.
- Breakaway Handle Design: American and Crescent design breakaway handles protect against excessive abuse and lever damage.
- Backset & Door Compatibility: Standard 2-3/4" backset; optional 2-3/8", 3-3/4", and 5" backsets available. Fits door thicknesses of 1-5/8" to 1-7/8" (K1704 spacer required for 1-3/8" doors).
- Latch & Strike Specifications: Latch #1834 with 1-1/8" x 2-1/4" front, 9/16" throw, and stainless steel nose. Strike #1135, 4-7/8" ASA curved lip.
- Electrified Operation: 100% duty cycle; 24V/AC supplied with bridge rectifier; 24V/DC at 0.21 Amps standard. 12V/DC optional. Request to Exit (REX) Switch available: single pole, double throw, 3 amp, 125 AC, wired normally open or normally closed (not standard).
- Cast Stainless Steel Retractor: Retractor is cast stainless steel with bronze roller bearings for ultra-high strength, smooth operation, and long service life.
- Solid Cast Zamac Levers: Levers are solid cast Zamac with 1/2" return. Rose is thru-bolted, 3-7/16" diameter, spring loaded with 2 #10 thru-bolts.
- Vibration-Proof Thru-Bolt Mounting: Thru-bolting with #10 epoxy-coated bolts ensures vibration-proof mounting with only two thru-bolts required for easy installation.
- Versatile Function Availability: Available in Passage, Privacy, Patio, Communicating, Entry, Exit, Classroom, Storeroom, Institution, Vestibule, Corridor, Store Door, Hospital/Privacy, Service Station Lock, Classroom Intruder, Dummy Trim, Communicating Passage, Communicating Storeroom, and Communicating Classroom functions.
