Usually the locking gas springs are installed in vertical direction, without locking in extension direction. A locking gas spring permits comfortable upward movements of applications, such as table tops, without the release actuation, which is made possible by a special valve system in the piston package.
More importantly, applications with a locking gas spring can stop anywhere in compression direction. Locking gas springs also boast simplified handling and safety. And they mainly apply to table adjustment systems in hospital nightstands and in school furniture.
