The lightweight OK carabiner is made of aluminum. It has an oval shape that allows optimal loading of devices with a wide section, such as pulleys or rope clamps. Its fluid interior design and Keylock system facilitate handling. It is available in two locking systems (automatic TRIACT-LOCK system or manual SCREW-LOCK system), or without a locking system.


Detailed description


  • Aluminum carabiner is lightweight to reduce equipment weight carried by the user
  • Symmetrical oval shape allows optimal loading of devices with a wide cross-section, such as pulleys, or rope clamps
  • 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
  • H cross-section:
    - ensures an optimal strength/weight ratio
    - protects markings from abrasion
  • Available without locking system, for easy clipping
  • Two locking systems available:
    - SCREW-LOCK: manual screw-lock with red band provides a visual warning when the carabiner is unlocked
    - TRIACT-LOCK: automatic locking with triple-action gate opening
  • May be used with a CAPTIV positioning bar to favor loading of the carabiner along the major axis, to keep it integrated with the device, and to limit the risk of it flipping


  • Material(s): aluminum
