- technique identical to 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 slack, thanks to the pulley mounted on sealed ball bearings and the separated and curved side plates - lower attachment hole is fixed to ensure alignment of the device with the axis of the worker and optimize grip 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 Rope compatibility: 11.5 to 13 mm diameter ZIGZAG allows the user to work in compliance with the ANSI Z133 standard Specifications ...
