The Petzl Zigzag Descender mechanical prusik is an innovative piece of equipment. This version has no swivel so gives you the rigidity that climbers have asked for, the Zigzag Plus version has the swivel if that is your preference. Tree surgery will never be the same once you have used the zigzag, it allows you to move freely around the tree whether ascending or descending. Branch walking can sometimes be a bit of a balancing act but with the Petzl Zigzag Descender it now becomes a joy, tending the slack is so easy as you move back into the tree.
Using the classic prusik pulley system the Zigzag is simple to move over to from the friction cord system. The pulley is mounted on sealed efficient ball bearings which allow slack to be taken up easily.
OPTIONS
SRT - The Zigzag can now be used for SRT when coupled with the Petzl Chicane
Intuitive to use:
- technique identical to the classic Prusik pulley system
- the device locks automatically on the rope once the friction chain extends
For efficient movement within the tree:
- rope feed is smooth and precise thanks to the release lever, allowing the user great control over his/her movements. Adjusting the pressure on this lever controls the speed of movement
- easy to take up the slack, thanks to the pulley mounted on sealed ball bearings and the separated and curved side plates
Versatile:
- for use on either doubled ropes or a single rope, thanks to the CHICANE accessory, which offers more friction on the descent, and the KNEE ASCENT assemblies, which facilitate the ascent
- upper attachment hole for the rope end when using a doubled rope or for the CHICANE auxiliary braking device when using a single rope. It has a flexible positioning ring that helps keep the connector oriented along its major axis
- - auxiliary attachment hole for adding a ZILLON lanyard or connecting a second system
Durability:
- steel construction for improved durability
- separated and curved side plates for better wear resistance
