With the ART Spiderjack 2 you can ascend or descend - slowly or very, very fast - your choice! The rope runs through the rope duct without any rope slackening (gain valuable points in competition) as soon as the moving rope is pulled above the Spiderjack device or the load on the rope is lifted. Rope re-directs are no problem (even in flat angles and through crotches). The blocking lever is made from a special wood with a high friction factor and the sensitivity can be easily regulated by pressure from the thumb. The user can choose between two different operating modes: walking along a limb the rope can be controlled by keeping the hand on the rope and the release/redirection lever; descending or swinging the passage of the rope can be controlled by the breaking lever - precision not seen before.
