Marks USA 195FB Communicating Storeroom Clutched Lever Lockset with Breakaway Handles, 2-3/4" Backset, Grade 1

The Marks USA 195FB is a Grade 1 Communicating Storeroom Clutched Lever Lockset engineered for demanding commercial applications. Supplied with 6-pin cylinders in Marks "C" keyway and 2 nickel-silver keys, this lockset features a cast stainless steel retractor with bronze roller bearings for ultra-high strength, smooth operation, and long life. The 195FB supports a standard 2-3/4" backset (with 2-3/8", 3-3/4", and 5" optional) and accommodates door thicknesses of 1-5/8" to 1-7/8" (use K1704 spacer for 1-3/8" doors). UL Listed and 3-hour fire rated, this lockset is built to exceed ANSI/BHMA standards in high-traffic commercial environments.

Key Features

• Exceptional Torque Resistance: Withstands torque of 1,800 inch-pounds — over twice the ANSI/BHMA (1996) test value — for superior durability under abuse.
• Proven Cycle Life: Life tested over 6 million cycles and fully operational after testing, ensuring long-term reliability in high-traffic applications.
• Clutch Mechanism: Features "The Clutch" — when locked, the clutch disengages the outside lever allowing it to turn freely without opening the latch, reducing torque on the outside lever and preventing the failures common with rigid lever locksets.
• Breakaway Handles: American and Crescent design breakaway handles protect against excessive abuse and forced entry attempts.
• 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 Specifications: Latch #1834 with 1-1/8" x 2-1/4" front, 9/16" throw, and stainless steel nose for corrosion resistance and smooth latching.
• Rose & Mounting: Thru-bolted rose, 3-7/16" diameter, spring loaded with 2 #10 thru-bolts; epoxy-coated bolts ensure vibration-proof mounting with only two thru-bolts for easy installation.
• Electrified Option: 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 on electrified leverset).
• Cylinder Options: Marks C keyway, 6-pin with 2 keys or IC Core housing for master key system compatibility.
