What is a locking tube?
 

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.

Black steel
 

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

Stainless steel
 

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

Material

Black steel
The black version is epoxy powder coated and thus resistant to corrosion.

Stainless Steel - AISI 304
If you need to use a locking tube in a wet or damp environment, however, we recommend that you use the stainless steel version.

Stainless steel - AISI 316
Used in constructions that are exposed to harsh cleaning agents or in maritime environments

Fitting And Use

The locking tube ensures that external elements such as wind, collisions, impacts, etc. do not cause a gate, for example, to close accidentally, risking injury to people or damage to property.

The function of the locking tube is easily neutralised with just one push.

Fitting And Use - Locking tubes

  1. When fitting the locking tube onto the gas spring it can be difficult to get the thread on the piston through the end piece of the locking tube. This is because of the spring-loaded end piece, which flips to the side to ensure correct spring function once.
  2. This is because of the spring-loaded end piece, which flips to the side to ensure correct spring function once.
  3. Press on the highest point of the end piece, and at the same time guide the piston through the hole in the end piece. Gas springs with a 6 mm piston are screwed into the end piece.
  4. The locking tube has now been fitted correctly, and the end fitting can be put on.
