Petzl OK Oval Carabiner

The symmetrical oval shape is specifically designed for loading devices with wide cross-sections, such as pulleys, rope clamps, and mobile fall arresters. Unlike D-shaped carabiners, the oval shape ensures these devices sit centered and stable, preventing them from shifting during use.

The H cross-section allows Petzl to remove excess material from the carabiner's body without sacrificing strength. This provides an excellent strength-to-weight ratio while also protecting the carabiner's markings from abrasion.

The CAPTIV bar is highly recommended if you want to ensure the carabiner stays loaded along its major axis. It keeps the carabiner integrated with your device, which significantly reduces the risk of the carabiner flipping or rotating into a cross-loaded position.

SCREW-LOCK is a manual system that requires you to screw the gate shut, making it ideal for environments where you don't need to open it frequently. BALL-LOCK and TRIACT-LOCK are automatic systems; BALL-LOCK uses a visual indicator to confirm it's locked, while TRIACT-LOCK is a three-stage automatic system designed for frequent, high-security use.

No, the OK carabiner features a fluid interior design and a Keylock system. This smooth, notch-free interface prevents the gate from catching on ropes, slings, or your harness gear loops during clipping and unclipping.
