Sargent CB1431 Replacement Door Closer Body | 1431 Series

The Sargent CB1431 Replacement Closer Body is the primary internal component for the heavy-duty Sargent 1431 Series Powerglide® surface-mounted door closer. Engineered for longevity in high-traffic commercial environments such as schools, hospitals, and office buildings, this replacement body allows you to restore full functionality to your existing door control system without the need for a complete new installation.

Constructed from a high-strength, one-piece aluminum silicon alloy with 14% silicon, the CB1431 offers superior wear resistance and structural integrity. It is designed for use on both interior and exterior doors and comes pre-filled with all-weather hydraulic fluid, ensuring consistent operation in extreme temperatures ranging from sub-zero winters to summer heat without needing seasonal valve adjustments.

High-Performance Hydraulic Control

• Adjustable Spring Power: Features a versatile Size 1 through 6 adjustable spring, allowing the closer to be field-tuned to the specific weight and draft conditions of your door.
• Precision Control Valves: Equipped with low-sensitivity brass valves for independent regulation of closing speed, latching speed, and backcheck intensity.
• Vandal-Resistant Design: All adjustment valves are recessed and operated by an 1/8" Allen wrench to prevent unauthorized tampering. Valves are captivated to prevent accidental removal from the body.
• Superior Construction: Utilizes a 1-1/2" diameter piston and heat-treated full rack and pinion to provide smooth, reliable control throughout the entire door cycle.

Technical Specifications

Compatibility & Installation

The Sargent CB1431 is a non-handed component, making it suitable for both left and right-handed door applications. It specifically retrofits older Sargent 1230 and 1231 Series installations, providing an easy upgrade path to modern Powerglide® performance.

• Application Note: This specific body model does not include the Delayed Action (DA) feature.
• Fastener Support: While this listing is for the body only, it is designed for use with standard machine and self-tapping screws. For wood or mineral core doors, the use of Sargent thru bolts is highly recommended to ensure a secure, long-term attachment to the door face.
• Maintenance Friendly: The front-facing valves allow for easy maintenance and adjustment once the closer is mounted.
