Norton 210 690 HDH Door Closer

The Norton 210 690 HDH is a manual hydraulic door closer built for interior and exterior openings that see heavy traffic. Its non-handed design suits parallel, regular or top-frame mounting without modification. The dark bronze painted finish over cast aluminium arms matches commercial aesthetics while meeting ANSI/BHMA A 117.1, ANSI/BHMA A 156.4, UL, cUL and ADA requirements.

Thermals Noise and Power Draw

Hydraulic operation means no electrical supply, so the unit adds zero power draw and produces no fan or motor noise during daily cycles. Fluid resistance governs closing speed, delivering consistent action regardless of temperature swings in the doorway environment. The cast aluminium arm dissipates heat from the hydraulic circuit passively, keeping performance stable in normal use.

Sustained Load Behaviour

Under continuous high-frequency operation the hydraulic fluid maintains viscosity, preventing the speed drift that can occur with lighter-duty closers. Hold-open function engages cleanly at the set angle and releases without binding when the door is pushed past the catch point. Ligature-resistant construction is not included, so facilities with that requirement should specify a different model.

Questions about this item

How do I install the 210 series closer with the parallel arm and what step is commonly missed?

Mount the body on the push side with the parallel arm bracket on the frame stop; the step often missed is setting the hold-open nut to the desired angle before tightening the arm shoe.

Which parts of the hydraulic 210 closer will need maintenance or replacement over time?

The hydraulic fluid seals and the cast aluminium parallel arm pivot bearings are the components that eventually wear and may require service or replacement.

What is the first performance limit that appears during sustained heavy use of this closer?

Under continuous high-cycle operation the hydraulic fluid temperature rises first, causing closing speed to vary until the unit cools.
