To go further

  • Over 35m, shackles and thick webbing we recommend the Fatlock
  • The line lock is to be used with carabiners, take care not to triload the carabiner. On trees over 1m50 of circonference the triloading can break your carabiner.
  • For longer lines or higher loads, we recommend using a "banana".


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.
