The PETZL VERTIGO TWIST-LOCK is a professional carabiner designed for use on progression lanyards and via ferrata sets. Its ergonomic shape and automatic locking system provide fast, safe, and comfortable handling when passing anchor points.

The carabiner is primarily intended for use with PROGRESS ADJUST or JANE lanyards. It can also be used with the TANGA positioning ring, which helps keep the carabiner loaded along its major axis and reduces the risk of cross-loading or twisting.

The TWIST-LOCK system automatically locks the carabiner when the gate closes and allows quick unlocking with a simple twist. The large gate opening and Keylock system make clipping easier and help prevent snagging during handling.

The H-profile construction provides an excellent strength-to-weight ratio while protecting markings from abrasion. The lightweight aluminium body ensures high durability with low weight.
