All about Gas Struts

Gas struts, gas springs, or gas shocks are mechanical devices that support, lift, or cushion the movement of various objects. Their applications include automotive hoods, trunk lids, industrial machinery, furniture, and more. Gas struts use the principles of fluid dynamics and gas compression to provide a controlled force that aids in opening or closing a mechanism.
