Sargent 1431 PS Powerglide® Door Closer | Heavy Duty Parallel Arm with Positive Stop
The Sargent 1431 PS Door Closer is a premium, high-security solution designed specifically for demanding commercial and institutional environments. Part of the industry-leading Powerglide® series, this ANSI/BHMA Grade 1 surface-mounted closer is equipped with a Heavy Duty Parallel Arm (PS) that includes a built-in positive stop. This integrated stop protects both the door and the adjacent wall by mechanically limiting the door's opening range from 85° to 110°, making it ideal for corridors or exterior doors where an overhead stop is not feasible.
Constructed with a heavy-duty, one-piece aluminum alloy body and a heat-treated full rack and pinion, the 1431 PS is engineered to exceed 25 million cycles. It features a non-handed design and adjustable spring power (sizes 1–6), ensuring it meets strict ADA accessibility requirements while providing the strength needed for heavy fire-rated doors. With its all-weather fluid, this closer delivers consistent hydraulic control in extreme temperatures without the need for seasonal adjustments.
Key Performance Features
- Positive Stop Protection: The forged steel PS arm provides a built-in mechanical stop, preventing the door from over-swinging and causing damage to hardware or the building structure.
- Superior Hydraulic Control: A large 1-1/2" diameter piston provides precise door control, complemented by separate brass valves for independent adjustment of closing speed, latching speed, and backcheck.
- Fire & Safety Certified: UL/cUL listed for use on fire-rated doors (up to 3 hours) and conforms to UL10C for positive pressure fire tests.
- Abuse Resistance: Standard pressure relief valves protect the door and frame from damage caused by forced closing or excessive wind.
- MicroShield® Antimicrobial Option: Available with a silver-based coating that suppresses the growth of bacteria, mold, and mildew—essential for healthcare and educational facilities.
- Retrofit Friendly: Designed to directly replace discontinued Sargent 1230 and 1231 series closers using existing mounting holes.
