How often will this application be used?

Please select the statement which best describes what you are trying to achieve:

When the lid is closed, it should stay closed and when it is open it should stay open, like a car boot.? The lid should always open automatically even when it is closed. The lid has a lock to keep it closed. (lid will need a catch)? The gas springs are only used to take some of the weight off. The lid should fall on its own at all times.

Do you require the spring to be mounted:

Inside, under the lid Outside, on the side of the lid Either
