Using advices

  • A shackle (with same size/weight) will be stronger (more resistant) than a carabiner.
  • If you use a soft release system, be careful to not unscrew the pin when releasing the tension into the soft release. Be careful with Soft Release System = pin's rotation
  • Works with most of the weblocks. Please check the compatibility and characteristics before any use.
  • Do not triload on the shackle pin = do not put the classic or round slings on the pin but on the bow. See picture below.
  • The Kit can stay in place for a few days, 2/3 max. It is better to release it after use.
  • Store your equipment clean and dry, as you will do for any other textiles pieces.


  • Don't tighten it on urban furnitures (bench, lamp, handrail)
  • Do not use as leverage furniture, slackline use only


Slacklining and more particularly Highline (in the void, secured by a harness) are sports practices that have no normative or regulatory framework for the manufacture of the material as well as for its installation.

This is why we do not guarantee our own equipment for highline use.
Our products are tested within our company and independent laboratories (mentioned on the product page) via a process that evolves with practice.

These resistance tests have no legal value, they aim to ensure the safety, resistance and comfort of use of our equipment - in the context of our practice.

It is the responsibility of the practitioner to choose the equipment with the appropriate resistance and to have the necessary experience to adapt the installation to his practice.
And to use appropriate equipment to secure oneself if necessary, such as PPE equipment (climbing gear, ropes, etc.).


  • Do not install your slackline across a path, trail or place of passage
  • Do not install your slackline more than 2m from the ground without securing yourself with PPE equipment
  • Practice on grassy or cushioned ground free of any protruding objects or objects that could cause injury
  • Do a back up = secure your tension system
  • Never use a ratchet for highline practice
  • Never install your slackline on urban furniture (benches, lampposts, barriers, etc.)

Safety regarding highlining

It is the responsibility of the practitioner to use appropriate equipment to secure oneself if necessary, such as PPE (climbing equipment, ropes, etc.).

In NO CASE is this equipment designed to secure itself. For the lifeline - called backup - we advise to use only PPE standard material (climbing material, ropes, etc).
Unless expressly mentioned, no slackline element can be considered as PPE (personal protective equipment) for sports and leisure activities
