The ZIGZAG PLUS mechanical Prusik allows the user to move around efficiently in a tree using classic Prusik pulley system technique. The friction chain provides precision and fluidity when moving around. The pulley is mounted on sealed ball bearings to allow the slack to be taken up easily. Can be used on either doubled ropes or a single rope, providing great versatility. The lower attachment hole with high-efficiency swivel ensures stable and correct positioning of the mechanical Prusik and optimal rope glide through the device. Description Intuitive to use: - 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 bearing
