Measure the height of the door or hatch in millimeters (mm). For hatch doors, measure from the top side to the bottom side. For boot lids or bonnets, measure from the back side to the front edge.

The recommended gas spring length is approximately 55%-60% of the door’s height. So, for a 1000mm door height, a 550mm-600mm gas spring would be suitable.

Gas Strut Length = Door Height × 0.55~06
