Petzl ZigZag Mechanical Friction Device (2022 model)

Petzl ZigZag Mechanical Friction Device

The Petzl ZigZag Mechanical Friction Device is designed to provide smooth and precise movement within tree climbing systems. It replicates the function of a traditional Prusik pulley system while offering enhanced control and consistency during positioning and descent.

The friction chain design allows fluid movement along the rope, with a release lever enabling accurate speed control during descent. A pulley mounted on sealed ball bearings supports efficient slack management, while separated and curved side plates improve durability and rope interaction. The device locks automatically when the friction chain extends, ensuring secure positioning without additional input.

Suitable for use on both doubled rope systems and single rope setups when used with compatible accessories, the ZigZag offers versatility for different climbing techniques. Its fixed lower attachment point maintains correct alignment with the user, improving handling and control. Built with aluminium, steel, and nylon components, it is compatible with 11.5 mm to 13 mm ropes and meets recognised standards for professional arborist use.
