Back in stock end November 2020

This carabiner has a twist lock gate. Very efficient, you can't let it open after the installation.
With his 24kN resistance and his oval shape, he is perfect for a slackline use, especially in the Primitiv Kits
The webbing passes trough it with ease. Connecting slings is ultra easy. A must have for kits over 50m in length. Above 50m or with a pulley system, we strongly recommend the use of shackles

Using advices

  • 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 destruction of the carabiner.
    To avoid this, please use shackles instead.


  • Trickline / Jumpline forbidden - Use shackles instead
    Carabiners can break due to fatigue failure, lear more here
  • Lines longer than 60m.
  • Triloading

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.
