Marks USA 195NB Communicating Passage Clutched Lever Lockset — Survivor Series with Lifetime Mechanical Warranty

The Marks USA 195NB is a commercial-grade cylindrical communicating passage lever lockset from the Survivor Series, engineered with a unique stainless steel clutch mechanism and bronze roller bearings that dramatically reduce wear, eliminate lever droop, and extend service life well beyond standard industry benchmarks. Designed for door thicknesses of 1-5/8" to 1-7/8" (with K1904 spacer for 1-3/8" doors), the 195NB supports both 2-3/8" and 2-3/4" backsets and carries a 3-Hour Fire Rating. The cast retractor on bronze roller bearings and solid cast zamac levers deliver a durable, lower-maintenance solution for high-traffic commercial environments, exceeding BHMA Grade 1 specifications by 300% — over 3.6 million cycles.

Key Features

• Exceptional Cycle Durability: Exceeds BHMA Grade 1 specifications by 300%, tested to over 3.6 million cycles for unmatched long-term reliability in demanding commercial applications.
• Unique Stainless Steel Clutch Mechanism: When locked, levers disengage from the retractor and interior mechanisms, swinging freely without resistance — eliminating lever droop and dramatically reducing component wear.
• Bronze Roller Bearing Construction: Cast retractors on bronze roller bearings provide a strong, durable chassis foundation that contributes to the lockset's millions-of-cycles service life.
• Backset & Door Compatibility: Accommodates 2-3/8" and 2-3/4" backsets; fits door thicknesses of 1-5/8" to 1-7/8"; use K1904 spacer 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 reliable latching performance.
• Thru-Bolted Rose Design: 3-7/16" diameter roses are spring-loaded and secured with 2 #10 thru-bolts for a solid, tamper-resistant installation.
