Product information

Pros and cons

This door closer is suitable for light and medium-weight doors weighing 40-100 kg. This makes it suitable for residential and semi-professional applications.

This door closer has a special backcheck function that protects your door against strong winds and acts as a kind of shock absorber.

You can adjust the force of the door closer after installation using the supplied Allen key.

This powerhouse has less power than its heavier brother such as the D3036, which means it works optimally with doors up to a width of 1250 mm and will be somewhat less powerful above that.

Description

Setting advice
Tip: Open the door all the way and tighten both adjusting screws on the door closer.
If you did it correctly, the door will now stay open and will not close again.
Now when you slowly turn the correct screw a little, the door will slowly close.
This allows you to determine the closing speed.
If you did it right, the door should not close all the way now.
If you now slowly turn the other screw you can determine the speed at which the door closes.
This way you can adjust the entire closing speed to your own preference.
