OK Ball-Lock Carabiner - Petzl

• Oval, symmetrical shape that allows for optimal positioning of large-diameter devices such as pulleys, ascenders, and pulley-ascenders.
  
• Makes handling easier:
  - a smooth interior design that minimizes the risk of a dead spot and facilitates carabiner rotation,
  - a Keylock system to prevent accidental snagging of the carabiner,
  - the H-shaped cross-section provides a better grip, protects markings from abrasion, and reduces weight.

- BALL-LOCK: an automatic locking system designed for frequent use, with a locking indicator. Triple-action opening: press the green indicator, rotate the ring, then pull the gate. The green visual indicator shows that the carabiner is locked.
