Descenders - Petzl Other | Professional


Descenders are designed to help regulate friction and control the descent on a fixed rope. They allow a worker to position himself at any point on the rope. Certain Petzl descenders can also be used as belay devices.

Self-braking descenders

Descenders with a self-braking feature and multi-functional handle allow the user to control the descent and to get into position without having to tie off the device. These devices are primarily designed for difficult to access work sites and rescue: for positioning at a work station or for movement along low-angle or horizontal terrain. The I’D S and I’D L descenders have an integrated anti-panic function and an anti-error catch. The RIG descender is designed for expert users.

Standard descenders

Mechanical Prusik for tree care

Mechanical Prusiks allow the user to move around efficiently in a tree while benefiting from the handling of a classic Prusik pulley system.

Mechanical Prusiks for tree care

Mechanical Prusiks allow arborists to optimize their movement within a tree. They are user-friendly and intuitive to use. To meet a variety of needs, they can be used on doubled rope and single rope.

Intuitive to use

Intuitive to use.

The technique is identical to that of a classic Prusik pulley system, and offers an intuitive grip. The device blocks automatically once the friction chain extends.

For efficient movement

Smooth, precise rope feed.

Smooth, precise rope feed

The release lever is mounted on a spring, for great precision when moving around. Adjusting the pressure on this lever controls the speed of movement.

Slack easily taken up.

Slack easily taken up

The pulley is mounted on sealed ball bearings to allow the slack to be taken up easily when moving around. The widely spaced side plates also contribute to smooth rope glide.


Use on doubled ropes.

Use on doubled ropes

ZIGZAG and ZIGZAG PLUS allow use on doubled ropes.

Use on a single rope.

Use on a single rope

They can also be used on a single rope, thanks to the CHICANE accessory, which offers more friction on the descent, and the KNEE ASCENT assemblies, which facilitate the ascent.
