The ART Spiderjack is smooth and efficient. The running rope is directly in front of the climber so it is possible to pull and feed the rope very comfortable with one hand or hand over hand into the device. Turning it in the releasing position and pressing the thumb brake needs very little force so speed regulation is very easy.
The integrated swivel allows the device to always be orientated in the optimum direction. There is a pulley under the body so the pull force from a deflected rope is smoothly absorbed in the device instead in the hand of the climber. It is not possible to place the cam accidentally the wrong direction. The large replaceable wearing pin inside the rope channel allows for working with the device for many years.
