Advantages and disadvantages

Dorrenhaus D-903 doorcloser with scissor arm (20-60 kg)

This compact Türschließer is suitable for light to medium-heavy doors weighing 20-60 kg. This makes it ideal for the majority of residential applications.
Equipped with a cover cap on the visible side over the adjustment screws, providing a neat, professional appearance. Because the adjustment points are on the front, this Türschließer is very user-friendly.
The arm is length-adjustable via a sliding mechanism, which makes installation simpler and faster.

This compact version has less power than heavier models such as the D2025 or the D3036. As a result, it works optimally with doors up to 1000 mm wide; with wider doors, the closing force decreases.

Description

This compact, durable door closer is ideal for professional use in homes, apartment buildings, and light commercial projects. Reliable performance, easy to install, and designed for long-lasting use.

Installation options

This door closer features an adjustable closing speed and final stroke.
This means you can set the first 150 degrees of the closing movement as you wish and adjust the last 30 degrees (final stroke) separately.
For example, you can choose a fast closing with a slow final stroke, or vice versa.

We have installed 12 of them in the sports hall. No more damage from playing football and it still works perfectly with the test alarm.

Sleek cover, neatly finished

The thermostat cover looks nice in the hallway. Children can no longer reach it and the material feels sturdy. The assembly video was helpful.

Heavy-duty door closer for exterior door

Our outside door always slammed shut. With this door closer, it closes smoothly, even in the wind. Adjusting the speed was child's play.

Protective cage for smoke detector

Sturdy metal cage. Protects against balls in the gym without blocking the alarm signal. Would have liked to see extra screws included in the box.
