The Arrow DCN516-3 690 Heavy-Duty Commercial Door Closer is an ANSI/BHMA Grade 1 hydraulic surface closer designed for demanding commercial and institutional applications.

Featuring a heavy-duty cast iron body, adjustable spring power sizes 1–6, parallel arm with positive dead stop, thumbturn mechanical hold-open, and full plastic cover, this closer provides dependable closing control and convenient hold-open operation for approved commercial door openings.

Part of the Arrow DCN500 Series, the DCN516-3 is engineered for high-traffic applications where durable construction and precise door control are essential.

The heavy-duty parallel arm includes a mechanical stop that can be installed at 85°, 90°, 100°, or 110° of door swing. Its thumbturn hold-open mechanism allows the door to remain open when required, while the hydraulic closer provides controlled closing after the hold-open function is released.

A hardened steel rack-and-pinion mechanism, high-tensile spring components, adjustable sweep and latch valves, and hydraulic backcheck provide consistent operation for commercial doors.

The 690 Dark Bronze Painted finish coordinates with bronze aluminum storefront frames, hollow metal doors, and dark commercial architectural hardware.

Designed for warehouses, retail establishments, commercial offices, institutional facilities, and approved service entrances, the Arrow DCN516-3 690 provides heavy-duty closing performance with mechanical hold-open convenience.

Important: This model includes a mechanical hold-open feature and is not appropriate for required self-closing fire doors.

How the Arrow DCN516-3 690 Works

1. Door Opening

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

2. Hydraulic Backcheck

The adjustable backcheck mechanism provides resistance as the door approaches its designated opening range.

3. Positive Dead Stop

The arm-mounted stop limits door travel at its installed position of 85°, 90°, 100°, or 110°.

4. Mechanical Hold-Open

The thumbturn hold-open mechanism can secure the door in the open position when needed.

5. Hold-Open Release

When the hold-open mechanism is released, the closer is able to resume its normal closing function.

6. Controlled Sweep Closing

The internal spring provides closing force while the hydraulic sweep valve regulates the main closing movement.

7. Latch-Speed Control

The independently adjustable latch-speed valve regulates the final portion of the door-closing cycle.

8. Door Relatching

The door returns to the closed position, allowing the compatible lock or latch mechanism to engage.
