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.

It can be used with all single ropes (optimized for 8.9 to 10.5 mm diameter ropes) and is suited for intensive use. The reduction handle offers exceptional descent control.

Petzl RIG Descender


The RIG allows the user to move into position then easily stop where needed. This descender is compact and intuitive to use, making for smooth descents. A simple and effective alternative to more traditional descenders. The RIG’s handle allows the user to switch quickly between descent and stopping for work. While the handle is in descent position, it will automatically return to belay position if the user lets go of it. This limits risks in case of involuntary operation of the handle, for example by user action, a falling object, etc.

The RIG is better-adapted for professional use. Pivoting cam facilitates taking up the slack in the rope. Can also be used to make a reversible haul system, and for short ascents (in conjunction with a FOOTPRO foot loop and an ASCENSION handled rope clamp). Single ropes between 10.5 and 11.5 mm in diameter (7/16” ). This device is for users that already have considerable experience. For professionals that are still learning technical rope access skills, we recommend the Petzl I’D Descender, which has additional safety features, such as an anti-panic function and an anti-error safety cam. Weighs 400 grams. Instructions included.
