The Osculati gas strut (also known as a gas spring) is made from stainless steel and features a vent valve, which allows the elevated standard push-in force of the spring to be customised depending on the weight of the hatch. The push-in force can be set when the strut is fully extended. The gas strut is fitted with stainless steel eyelets at each end that have an 8mm bore. The gas spring comes supplied with a key for the vent valve.
