Using advices

  • A shackle (with same size/weight) will be stronger (more resistant) than a carabiner, but less convenient to use.
  • 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 particularly Highlining are sports having no legal framework or norms concerning the gear or the setup.

Consequently we cannot warranty our gear for Highlining.
Our products are tested by independent labs (Apave) and inside of our company via a process evolving with practice.

The results of those tests have no legal values, they aim to ensure the safety and comfort of using our equipment.

It is the responsibility of the slackliner to choose the right gear with adequate resistance and to have the necessary experience to adapt his installation to his practice.


  • Don't rig your slackline accross a path,a road or any crossing
  • Don't rig your slackline higher than 2m
  • Ride on a grassy or soft ground, without roots or rocks
  • Always backup your setup
  • Never use ratchets for highlining
  • Never use urban furniture as anchor point

This equipement is absolutely not made for highlining. Find more information on our website
