Using advices

  • Unlock (unscrew) the ring of the screw carabiners before unset your slackline to avoid blocking the mechanism induced by the deformation under tension.
  • Useful to connect slings to the slackline and for Primitiv Kits
  • Use it only in the right direction - never sideways
    • Triloading : Avoid to use it when your sling is connected round a big tree. If you still do it, it will affect the resistance of the carabiner due to a triload force which can lead to the break of the carabiner.
