Detailed description


  • High-strength steel carabiner for use in harsh environments, particularly suitable for setting up anchors or for connecting to metal structures
  • Large-capacity, asymmetrical shape facilitates connecting multiple items, especially when setting up multi-anchor systems
  • Large opening for connection to thick anchors
  • Easier handling:
    - fluid interior design limits the risk of having a catch point and facilitates rotation of the carabiner
    - Keylock system to avoid any involuntary snagging of the carabiner
