Knee ascender assembly with foot loop to facilitate ascents on a single rope, for tree care
The KNEE ASCENT LOOP assembly facilitates the arborist’s ascent when using the ZIGZAG or ZIGZAG PLUS mechanical Prusik on a single rope. It contains an upper strap, a CROLL L rope clamp, a lower strap with foot loop and an XS size TOOLBAG tool pouch. The system is entirely adjustable and adapts to all shapes and sizes.
Auxiliary brake for mechanical Prusik on single ropes, for tree care
The CHICANE auxiliary braking device allows ZIGZAG and ZIGZAG PLUS mechanical Prusiks to be used on single ropes. It provides continuous additional friction on descents. The excellent compatibility of the CHICANE and mechanical Prusik as an assembled unit ensures smooth rope glide through the brake during ascents. The ergonomic handle provides excellent grip and facilitates movement while limb walking. Thanks to the openable side plate, installation is quick and easy.
Please note: most carabiners will not fit through the chicane. You will require a Petzl OK or Petzl Am’D connector.
Mechanical Prusik with high-efficiency swivel, for tree care
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.
For use with ropes in accordance with EN 1891 from 11-13 mm. With the SpiderJack, unlike with the LockJack, there is no need to change the rope grab for ropes from 11 to 13 mm diameter.
