A - The length of the gas spring in its extended state.
B - The length of the pipe (without end fitting).
C - The length of the rod (without end fitting)
D - The diameter of the pipe
E - The diameter of the rod
F - The force of the gas spring. Force is measured in Newtons (N).
Example: F=200N
In case the force is not marked on the gas spring, let us know the approximate weight of the burden that gas spring lifts.
G - The type of end fitting. (You can find types of end fittings
here.)
