The Arrow DCN516-3 689 Heavy-Duty Commercial Door Closer is an ANSI/BHMA Grade 1 hydraulic surface closer engineered for dependable closing performance 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 thumbturn mechanical hold-open, the DCN516-3 provides precise door control with the convenience of an adjustable hold-open function.

Part of the Arrow DCN500 Series, this closer is specifically configured for push-side parallel-arm mounting on compatible commercial doors. Its heavy-duty arm features a positive stop that can be installed at 85°, 90°, 100°, or 110°, helping control door opening travel.

The integrated thumbturn hold-open mechanism allows the door to remain open when needed and permits normal hydraulic closing after the mechanism is released.

Built with a hardened steel rack-and-pinion mechanism, high-tensile steel springs, hydraulic sweep and latch-speed adjustments, and adjustable backcheck, the Arrow DCN516-3 is designed for consistent commercial service.

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 commercial hollow metal doors, aluminum storefront systems, and satin aluminum architectural hardware.

Ideal for warehouses, retail establishments, commercial offices, maintenance facilities, and approved institutional service openings, the Arrow DCN516-3 689 delivers heavy-duty closing performance with convenient mechanical hold-open capability.

Important: This model includes a mechanical hold-open arm and must not be used where a fire door is required to close automatically.

How the Arrow DCN516-3 689 Works

1. Door Opening

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

2. Opening Control

The opening movement is controlled by the arm geometry and appropriately adjusted hydraulic components.

3. Positive Dead Stop

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

4. Thumbturn Hold-Open

When engaged, the mechanical thumbturn hold-open retains the door at the designated position.

5. Hold-Open Release

The hold-open function must be released before normal closing can resume.

6. Hydraulic Sweep Closing

The spring supplies the closing force while the hydraulic sweep valve controls the main closing movement.

7. Latch-Speed Control

The independently adjustable latch valve regulates the final closing movement.

8. Door Relatching

The door returns to its closed position, allowing the compatible latch or locking hardware to engage.
