Petzl Descenders

Petzl's descenders are amongst the most widely used descent devices in the world, and range in scope from the Pirana, a figure-8 style device with unique hyper horns to the I'D, a belay device with anti-panic features and simple operation. Petzl's descenders are used in tree climbing, rock climbing, military operations, fire and rescue, and more. The years of design and testing that have gone into Petzl's descent devices have produced a range of user-friendly descent devices that bring ultimate function and security to the job.

Petzl Pirana Descender


The Petzl Pirana is a unique descender with three different braking positions, two supplementary braking spurs, and a small carabiner hole for a “rigid” carabiner/descender unit which helps to keep the descender positioned correctly. The carabiner hole will only fit Petzl carabiners, and is meant to be a tight fit.
