Sargent 351-CPSH Tb En Surface Door Closer Parallel Arm

Product Description

The SARGENT 351-CPSH TB EN is a surface-mounted door closer designed for heavy-duty commercial and institutional applications. It features a hold-open parallel arm configuration with a compression stop, giving installers precise control over door positioning and preventing the arm from overextending under load. The unit is finished in sprayed aluminum enamel for durability in high-traffic environments. Thru-bolt mounting hardware is included, providing a secure fastening method suited to hollow metal and solid-core wood doors. This type of closer is typically installed by commercial door and hardware technicians or general contractors working on commercial fit-outs.

This door closer is suited for commercial entryways, institutional corridors, and high-traffic openings where a parallel arm mount is required to keep the closer body on the push side of the door. The hold-open feature allows the door to remain open at a set position without manual intervention, which is useful in warehouse, healthcare, and educational facility settings. The compression stop limits arm travel to protect the hardware and the door frame during hard openings.

Key Features

• Heavy-duty surface-mount construction rated for high-cycle commercial use
• Hold-open parallel arm allows door to stay open at a set position
• Compression stop protects hardware and frame by limiting arm overtravel
• Thru-bolt mounting provides a more secure attachment than standard wood screws
• Sprayed aluminum enamel finish offers corrosion resistance and a clean appearance

Compatibility

Designed as an OEM-style replacement or new-installation surface door closer for commercial-grade hollow metal and solid-core wood door assemblies requiring a parallel arm mount configuration.

Installation Notes

Installation should be performed by a qualified door hardware technician or licensed contractor familiar with commercial door closer mounting requirements. Disconnect or isolate any access control or electrified hardware on the door before beginning work. Thru-bolt installations require drilling completely through the door or frame, so verify door construction before starting. Follow the closer manufacturer's template and applicable local building codes for proper arm geometry and closing force adjustment.
