  • May be used with a CAPTIV positioning bar to favor loading of the carabiner along the major axis, to limit the risk of it flipping and to keep it integrated with the device.

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 improved strength-to-weight ratio.
  • Protects markings from abrasion.
