Installation recommendation: Gas strut

Total weight 25kg = 2 x 12.5kg

Enter the total weight of the flap here. To determine the weight of an assembled flap, proceed as follows: Hold the flap horizontally and weigh the end facing you with the hinge side facing away from you. The total weight of the flap is twice the measured weight. Note: This method is only suitable for simple rectangular flaps.

Indicates the desired operating force or the maximum operating force. Up to 10 kg, the application can be operated several times in succession by anyone. At 20-30 kg, it is very difficult for one person to operate the application.

Enter the desired opening angle here (from fully closed to fully open).

Download our paper protractor or use your cell phone or tablet to measure the angle when closed and open.

Tragen Sie hier den Winkel in Grad ein, wenn die Klappe geschlossen ist (ausgehend von der Waagerechten, siehe Abbildung). Sie können unseren Winkelmesser aus Papier herunterladen oder den geschlossenen und geöffneten Winkel mit Ihrem Smartphone oder Tablet messen.

Indicate the length of the flap. To do this, measure the side on which the pivot point is not located. (see illustration).

Please select the desired number of gas struts here. As a rule, we recommend using two gas springs - one on each side of the flap. Alternatively, it is also possible to use just one gas spring, although in some cases this can lead to the flap warping or not closing completely at the fastening point. To avoid this, the gas spring should be attached to the center of the flap.

Enter the thickness or height of your gas spring application in millimetres here (see illustration, the flap is shown here according to this thickness/height). If the flap has edges, please enter the height of these edges. This information is crucial for correctly calculating the flap's center of gravity and determining the optimum attachment point.
