Petzl Vertigo Twist-Lock

This carabiner is specifically engineered for use on the ends of progression lanyards. Its design is optimized for environments where you need to frequently manipulate the carabiner, such as passing intermediate anchors on a via ferrata or during rope access work.

The TWIST-LOCK is an automatic locking system. To open the gate, you simply twist the sleeve and pull the gate open; once you release it, the gate locks automatically. This is ideal for scenarios where you need to clip and unclip repeatedly without worrying about manually locking the carabiner.

No, it features a Keylock nose design, which is a snag-free system. This prevents the carabiner from catching on ropes, slings, or your harness gear loops when you are clipping or unclipping.

Not at all. The H-profile is a functional design choice that protects the carabiner's markings from abrasion. This ensures that critical safety information and the unique identification code remain legible over the long term, which is essential for equipment inspections.

While it is CE EN 362 certified and strong enough for many professional applications, it is primarily designed for lanyard progression rather than as a primary belay or climbing carabiner. Always check your specific activity requirements against the carabiner's 25 kN major axis strength rating.
