Petzl Ascenders and Rope Grabs

Petzl ascenders are used in tree climbing around the world. The popular handled Ascension and the Pantin foot ascender are some of our most popular ascenders for tree climbing. All Petzl tree climbing gear is designed for top-performance and maximum safety and backed by a 3-year manufacturer guarantee.

Petzl Zigzag Mechanical Prusik - 2014 Model

ASC181

The Zigzag mechanical prusik for arborists combines all the individual pieces of gear being used in doubled rope climbing into one slick device. The Zigzag functions like a prusik, slack tending pulley, and swivel all in one.

Friction is managed by running the climbing line through the linked "zig-zag" pattern of rings. The top ring is a lever, and pushing down on this lever releases pressure in the rings, and the climber descends - just like using a prusik cord. Release the lever and the Zigzag jams, stopping descent. The climber has control over the rate of descent through varying the pressure on the Zigzag lever.

Climbing on the Petzl Zigzag is just like climbing on your prusik and pulley, but with all of your hardware integrated into a single mechanical prusik.
