Sargent 351-CPS Tb En Surface Door Closer Parallel Arm

Product Description

The SARGENT 351-CPS TB EN is a heavy-duty surface-mounted door closer designed for commercial and institutional door applications. It features a parallel arm mounting configuration with a compression stop, which controls the door's open position and prevents the arm from over-traveling. Thru-bolt hardware is included for a secure, pull-side mount through the door. The closer ships in a sprayed aluminum enamel finish, making it suitable for aluminum storefront frames and painted hollow metal doors. Licensed door hardware technicians and commercial locksmiths are the primary installers for this type of hardware.

This closer is suited for heavy-duty commercial installations where parallel arm mounting is required - typically on doors where the closer body must mount on the push side of the door with the arm extending to the frame on the opposite side. Common applications include office buildings, schools, hospitals, and other facilities requiring controlled door swing and positive latching. The compression stop feature limits the door's opening arc, protecting adjacent walls and hardware from impact damage.

Key Features

• Heavy-duty parallel arm mounting configuration for push-side closer body installation
• Compression stop controls maximum door open angle and prevents over-travel
• Thru-bolt fasteners included for secure attachment through the door face
• Sprayed aluminum enamel finish coordinates with aluminum storefront and hollow metal door frames
• Surface-mount design simplifies installation compared to concealed or overhead-concealed closers

Compatibility

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

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial locksmith in accordance with ANSI A156.4 door closer standards and the door manufacturer's hardware prep requirements. Before installation, verify the door and frame are properly prepped for thru-bolt mounting and that the closer size is appropriate for the door width and weight. Adjust closing speed, latching speed, and backcheck hydraulic controls with a standard hex key after mounting. Do not over-drive thru bolts, as this can distort the closer body and affect fluid seal integrity.
