Gas Spring Pneumatic Stay -10 kg/22 lbs OS01-17 but it has a lotGas Springs provide silent, effortless precise and reliable movement unattainable with stays using metal springs or friction to control motion. The stays, usable on both down moving and up moving lids, are simple to install. The mounting brackets are applied to the case and the lid separately and the body of the stay just snaps on. Pneumatic stays are rated by closing force in pounds. You will need to find the correctly rated stay for your project.
