About the gas springs, which do I need for my specific situation and is there a manual available?

Our gas springs are a real do-it-yourself product. They are usually used to open a lid on a box or hatch more easily. Do not start without the necessary experience with DIY jobs! All available information about our gas springs can be found on the relevant product page. Regarding the choice of the gas spring, it usually comes down to figuring out (for example through the use of a scale) how much force is needed to lift the lid at the point where the gas spring will be mounted. For example, a 250N gas spring can lift 25 kg. The lid must of course remain open and not fall down, so with 25 kg weight a 350N gas spring will probably be the better choice.

Unfortunately, we do not advise customers further on the required strength and installation methods of gas springs. It is very dependent on the specific situation. There are however online installation videos and calculation modules everywhere on the internet.

We have a document available that shows all the gas springs we sell, please have a look: wtd_gassprings.pdf
