Sargent 351 CPS Powerglide® Door Closer | Heavy Duty Parallel Arm with Compression Stop
The Sargent 351 CPS Door Closer is the definitive solution for high-traffic openings that require maximum protection for both the door and the adjacent architecture. As a standout in the Powerglide® series, the 351 CPS features a Heavy Duty Parallel Arm with an integrated Compression Stop. This specialized spring-cushioned stop provides a "dead stop" within 3 degrees of the selected opening angle (adjustable between 85° and 105°), absorbing the shock of violent openings to prevent damage to walls, frames, and hinges.
Engineered with a heavy-duty, one-piece die-cast aluminum silicon alloy body (containing 14% silicon), this ANSI/BHMA Grade 1 closer is built to withstand extreme use in environments like schools, hospitals, and busy commercial corridors. The heat-treated full closed rack and pinion mechanism ensures precise hydraulic control from a wide-open position through the final latching phase.
Elite Engineering & Durability Features
- Cushioned Compression Stop: The forged steel CPS arm includes a robust spring-cushion that prevents the door from slamming against a hard stop, significantly extending the life of the door and hardware.
- Precision Control Valves: Features separate, low-sensitivity brass valves for closing speed, latching speed, and backcheck. All valves are adjusted with a simple 1/8" Allen wrench and are captivated to prevent accidental removal.
- All-Weather Reliability: Pre-filled with all-weather hydraulic fluid, allowing the closer to maintain a consistent speed in temperatures ranging from sub-zero winters to scorching summers without manual adjustment.
- High-Strength Piston: A massive 1-1/2" diameter piston provides superior door control and the durability required to exceed 25 million cycles.
- Safety & Code Compliance: UL/cUL listed for use on fire-rated doors (up to 3 hours) and compliant with UL10C and UBC 7-2 positive pressure standards. Fully ADA compliant for easy accessibility.
- Optional MicroShield® Finishing: Available with an antimicrobial silver-based coating that permanently suppresses the growth of bacteria, algae, and mold.
