Sargent 125-V Support Bracket — For 1431, 351 & 281 Series Door Closers
The Sargent 125-V Support Bracket is a heavy-duty mounting accessory designed to provide a secure fifth screw-hole anchor point for parallel arm and compression-stop arm configurations on Sargent surface-mounted door closers. Required for specific arm types and narrow stop conditions, this bracket ensures proper load distribution and long-term closer performance on commercial door applications.
Key Benefits
- Required for heavy-duty arm types — Provides the essential 5th screw hole needed for PS, PSH, P10, PH10, CPS, and CPSH parallel/compression-stop arms that cannot be secured with the standard four-hole pattern alone.
- Mandatory for narrow door stops — Required whenever the door stop width is less than 3 inches, preventing arm flex and ensuring the closer assembly stays rigid under repeated cycling.
- Broad closer compatibility — Fits the Sargent 1431 Series, 351 Powerglide Series, and 281 Series surface door closers, covering a wide range of commercial interior and exterior door applications.
- Two finish options — Available in EN (Aluminum Enamel) and EB (Bronze Enamel) to coordinate with door and frame finishes in commercial, institutional, and healthcare environments.
Compatible Arm Types
The 125-V bracket is specifically designed for use with the following Sargent arm configurations:
- PS — Parallel Arm with Positive Stop
- PSH — Parallel Arm with Positive Stop and Hold Open
- P10 — Parallel Arm (Hold Open, up to 180°)
- PH10 — Parallel Arm Hold Open variant
- CPS — Compression Stop Parallel Arm
- CPSH — Compression Stop Parallel Arm with Hold Open
These are all heavy-duty parallel arm types used in high-traffic commercial doors, OR corridor doors, and fire-rated door assemblies where the closer must deliver consistent positive-stop or hold-open function.
Applications
- Commercial office buildings and institutional facilities requiring parallel arm closer installations
- Healthcare and hospital corridor doors where P10 or CPSH arms are specified for magnetic hold-open systems
- Any door where the stop width is under 3 inches — a condition that makes this bracket mandatory, not optional
- Replacement and retrofit installations on existing Sargent 351, 1431, or 281 closer assemblies
