Sargent 351-CPS Mc En Rh Surface Door Closer Parallel Arm

Product Description

The SARGENT 351-CPS MC EN RH is a heavy-duty surface-mounted door closer designed for commercial and institutional door applications. Built with a parallel arm configuration and a compression stop, it controls door swing and prevents the door from opening beyond the set limit. The metal cover protects the closer body and internal components from dust and impact damage. Finished in sprayed aluminum enamel, it suits aluminum storefront and hollow metal door frames commonly found in commercial construction. This closer is installed by commercial door hardware technicians and general contractors working to ADA and local building code requirements.

This door closer is suited for commercial entry doors, interior corridor doors, and institutional applications where controlled door swing and a clean finished appearance are required. The parallel arm mount allows the closer to be installed on the push side of the door without the arm projecting into the clear opening, making it a common choice for high-traffic vestibules, office entries, and public building corridors. The compression stop limits the door opening angle and protects adjacent walls and door hardware from impact damage.

Key Features

• Heavy-duty construction rated for high-traffic commercial door applications
• Parallel arm configuration mounts on the push side without reducing clear opening width
• Compression stop limits door travel and prevents wall and hardware damage
• Metal cover shields closer body from dust, debris, and incidental impact
• Sprayed aluminum enamel finish coordinates with aluminum storefront and hollow metal frames

Compatibility

Designed as an OEM-style replacement or new-installation surface door closer for commercial hollow metal and aluminum-framed doors requiring a parallel arm mount with compression stop.

Installation Notes

Installation should be performed by a qualified door hardware technician or commercial carpenter familiar with ANSI A156.4 door closer standards. Disconnect or de-latch the door before adjusting spring tension or arm position. Use manufacturer-supplied fasteners and verify door thickness and frame reinforcement are adequate for the closer mounting pattern. Closer sweep, latch, and backcheck valves should be adjusted only after the unit is fully fastened to the door and frame.
