Closing & latching speed

The closing speed from maximum opening angle to 15° and the latching speed from 15° to 0° can easily be controlled by two independent valves on the top of the closer.NHN Series 480

Back-check function (optional)

This function is built into the track of the slide arm and gives a cushion effect to the outward swing of the door. Most suited where the opening door might hit a wall ie. in a corridor, or where it could injure someone if it opens too quickly. It is recommended for use on externally opening doors in windy environments.

The back check function is adjustable within the track. Recommended angle is between 70° and 85°.


NHN Series 480-2


For adjustment the closing speed screw and the latch speed screw are located on the top of the closer body.

The power adjustment screw by no. 480 Series is located at the short side of the closer body. The manual shows the setting and the number of turns required to change the power force of the no. 480 closer body.

The no. 480 series door closers are designed to allow a door opening angle of 110° by using butt hinges with a maximum offset of 10mm. Using the door closers in top jamb application or using hinges with a different offset can limit the maximum opening angle of the door.

It is recommended to fit always a door stop.
