Petzl OMNI Carabiner

The semi-circle geometry is specifically designed for multidirectional loading. Unlike standard carabiners that are meant to be loaded along the major axis, the OMNI allows you to securely unify multiple attachment points, such as connecting a harness to a ventral rope clamp, without the risk of cross-loading.

While it is a specialized tool, it is perfectly safe for climbing applications where you need to connect multiple components to a single harness point. However, because of its unique shape and intended use for complex rigging, it is less versatile than a standard locking carabiner for general tasks like clipping quickdraws.

Yes, the H-frame profile is a smart design choice that optimizes the strength-to-weight ratio. It keeps the carabiner lightweight while providing excellent durability, and it also helps protect the laser-etched markings from abrasion, ensuring they remain readable over time.

The Keylock system features a smooth, snag-free nose design that prevents the carabiner from catching on your harness webbing, ropes, or other gear. It makes clipping and unclipping much smoother, especially when you are working in tight or complex rigging setups.

Both versions are built to the same high standards and share the same major axis strength rating of 20 kN. The primary difference is operational: the screw-lock requires manual tightening, while the automatic gate provides an extra layer of security by locking itself, which is often preferred for critical rescue applications.

The manual screw-gate models feature a visual locking indicator. When the gate is unlocked, a red band is visible near the gate opening; once you screw the sleeve down and cover that red band, you know the carabiner is securely locked.
