Petzl ZIGZAG Mechanical Prusik, 2014 Edition

The ZIGZAG allows you to efficiently move around in a tree using classic Prusik pulley system technique. Friction links provide progressive braking action, and varying the pressure on the release lever precisely controls the speed of descent. The pulley is mounted on sealed ball bearings to allow slack to be easily taken up. A swivel constantly keeps the device in position for better rope glide. Features steel construction, an upper connection point to easily connect the end of the double rope, and a flexible ring that maintains the connector in the major axis position. Only for use on double ropes.
