Sargent 1431 UH Powerglide® Door Closer | Universal Friction Hold Open Arm

The Sargent 1431 UH Door Closer is a high-performance, Grade 1 commercial door closer engineered for maximum versatility and durability. As part of the prestigious Powerglide® series, the 1431 UH features a Universal Friction Hold Open Arm, allowing the door to be secured in an open position at a user-defined angle. This "one-box" solution is designed for Regular, Top Jamb, or Parallel Arm mounting, providing facility managers and contractors with the ultimate flexibility for nearly any door application.

Constructed from a high-silicon aluminum alloy with a heat-treated full rack and pinion, this closer is built to withstand the rigors of high-traffic institutional settings like schools and hospitals. The 1431 Series is UL/cUL listed for use on fire doors and features adjustable spring power from Size 1 to 6, ensuring compliance with ADA accessibility standards while maintaining the strength to control heavy exterior doors.

Technical Specifications

Architectural Compatibility & Innovation

The Sargent 1431 UH is designed to meet the highest standards of life safety and accessibility. For healthcare and food service environments, it is available with the MicroShield® antimicrobial coating, which permanently suppresses the growth of bacteria and mold. The non-corrosive plastic cover is standard, though optional metal and lead-lined covers are available for specialized security or medical imaging applications.

The Sargent 1431 UH ensures that your facility remains safe, secure, and easy to navigate. By utilizing a 1/2" arm engagement over a 7/16" square spindle, Sargent provides a wear-resistant joint that prevents the loosening often found in inferior commercial closers.
