How do I calculate the Newton value for a cover?

L1*=Kg (Total weight in kg)*=
L2*=N (Number of gas springs) =

Your Newton value will be:

Instructions:
Fill in the values. All fields L1, L2, Kg and N must be filled in. Click on “Calculate”.

* L1 is measured from center of the hinge (O).

* L2 is measured from the hinge´s center (O) to the closest fix point of the gas spring when cover is open.

* The weight refers to the total weight of the cover.
To get total weight of the cover: Remove gas springs, put a scale in the opening at the back. Close the cover on to the scale and double the value.
