A locking tube is used as a safety device in structures with gas springs. The locking tube stops the gas spring closing unexpectedly. This may be in the event of a gust of wind, distortion of the gas spring, a leaking gasket, increased load on the structure, etc.

Note: Locking tubes can only be used together with gas springs with threads.

The black version of the locking tube has been given an epoxy powder coating. This provides a degree of rust protection.

If you need to use a locking tube in a wet or damp environment, however, we recommend that you use the stainless steel version.

Used in constructions that are exposed to harsh cleaning agents or in maritime environments

The piston rod of the gas spring must be inserted into the locking tube and the thread must pass through the hole in the end of the locking tube. You can tilt the plate at the bottom so that it is easier to get the thread through. Then screw the end-fitting on. The tilt function will always try to make the tube strike against the piston rod and so prevent the gas spring from closing unexpectedly, as the cylinder will strike the edge of the locking tube and the movement will be stopped. Before closing the door – i.e. before the gas spring can be compressed – the locking tube must be released by pushing it out of the piston rod so that the cylinder can move freely into the locking tube.
