The Arrow DCN516-2 689 Heavy-Duty Commercial Door Closer is an ANSI/BHMA Grade 1 hydraulic surface closer engineered for reliable, controlled door closing in demanding commercial and institutional environments.

Featuring a heavy-duty cast iron closer body, adjustable spring power sizes 1–6, reinforced parallel arm with positive dead stop, and standard non-hold-open operation, the DCN516-2 delivers dependable closing performance with controlled door-opening travel.

Part of the Arrow DCN500 Series, this closer is designed for push-side parallel-arm installations requiring a durable mechanical stop to limit the maximum door-opening angle.

The heavy-duty arm can be installed with a positive stop at 85°, 90°, 100°, or 110°, allowing installers to select the appropriate door-opening limit for the application.

Unlike a mechanical hold-open closer, the DCN516-2 automatically returns the door toward its closed position when released, making it suitable for commercial openings where a non-hold-open closing function is required.

Built with a hardened steel rack-and-pinion mechanism, high-tensile steel springs, adjustable sweep and latch-speed valves, and hydraulic backcheck, the Arrow DCN516-2 provides controlled operation under frequent commercial use.

The included full plastic cover conceals the closer body and provides a clean architectural appearance.

Finished in 689 Aluminum Painted or Powder-Coated, this model coordinates with hollow metal doors, aluminum storefront systems, and commercial architectural hardware.

Ideal for commercial offices, educational facilities, warehouses, retail establishments, healthcare buildings, and institutional properties, the Arrow DCN516-2 689 provides heavy-duty hydraulic closing performance with positive opening control.

Important: This is the non-hold-open dead-stop model. The DCN516-3 includes a thumbturn mechanical hold-open feature and is sold separately.

How the Arrow DCN516-2 689 Works

1. Door Opening

As the door is opened manually, the heavy-duty parallel arm operates the closer's internal rack-and-pinion mechanism and compresses the closing spring.

2. Hydraulic Backcheck

The adjustable backcheck mechanism provides resistance during the designated opening range.

3. Positive Dead Stop

The arm-mounted stop limits the door's travel at the selected opening position of 85°, 90°, 100°, or 110°.

4. Automatic Spring-Powered Closing

When the door is released, the spring begins returning the door toward its closed position.

5. Controlled Sweep Closing

The hydraulic sweep valve regulates the main portion of the closing cycle.

6. Latch-Speed Control

The independently adjustable latch valve controls the final closing movement.

7. Door Relatching

The closer completes the closing cycle, allowing compatible locking or latching hardware to engage.

Unlike the DCN516-3, the DCN516-2 does not have a thumbturn or mechanical hold-open mechanism.
