Sargent 351 P10 Powerglide® Door Closer | Heavy Duty Parallel Arm
The Sargent 351 P10 Door Closer is a flagship hydraulic closer specifically designed for high-abuse, high-traffic commercial and institutional settings. As part of the world-class Powerglide® series, the 351 P10 features a Heavy Duty Forged Steel Parallel Arm (P10) that provides superior strength and rigidity for push-side installations. This model is engineered to withstand the rigorous demands of schools, hospitals, and government buildings, ensuring reliable door control and long-term durability.
Constructed with a one-piece die-cast aluminum silicon alloy body (containing 14% silicon content), the 351 body offers exceptional wear resistance and structural integrity. Its heat-treated full closed rack and pinion ensures total control of the door from the fully open position down to the final latch. With adjustable spring power from Size 1 to 6, this "one-box" solution is easily tuned in the field to meet ADA accessibility standards or to handle heavy exterior doors under high wind conditions.
Industrial-Grade Performance & Safety Features
- Forged Steel P10 Arm: The heavy-duty parallel arm is significantly stronger than standard stamped arms, offering increased resistance to vandalism and heavy use.
- Superior Hydraulic Precision: A massive 1-1/2" diameter piston provides the highest level of hydraulic door control, while separate brass valves allow for precise tuning of closing speed, latching speed, and backcheck.
- Tamper-Resistant Engineering: All adjustment valves are controlled by an 1/8" Allen wrench and are captivated within the body to prevent accidental removal or damage.
- Extreme Climate Versatility: Pre-filled with all-weather hydraulic fluid, the closer maintains a consistent closing cycle in temperatures ranging from extreme winter cold to scorching summer heat without manual adjustment.
- Fire & Accessibility Compliance: UL/cUL listed for use on fire doors (up to 3 hours) and compliant with UL10C and UBC positive pressure tests.
- MicroShield® Antimicrobial Option: Available with a silver-based finish that permanently suppresses the growth of bacteria, algae, and mold.
