The newest innovation from ART (Advanced Rope Techniques), the SpiderJack is an improvement of the popular Lockjack. By allowing slack in the line above to fall through the device with even less friction, the SpiderJack makes ascents in the doubled rope technique even easier. In addition, the SpiderJack also allows finer control over friction during descents, making tasks such as limb walking even easier by permitting the user to vary friction more subtly than before. Smooth friction surface.

Works with 7/16” - 1/2” rope.

Safe Usage Tips

  • Using the SpiderJack requires wearing a harness with a low attachment point. The lower the SpiderJack is attached, the longer are the arm pull movements.
  • The SpiderJack has no panic-function! Therefore it is necessary to follow user instructions especially in the learning phase!
  • We need to inform you about a potential operating error with the Dyneema-Kit on the SpiderJack 2.1. Recently, a climber had not clipped the stainless steel ring of the Dyneema-Sling into his lower Carabiner by mistake. That way he hung with half of his weight on the little screw (15 in the manual) which fixes the guiding flange (#16) of the Dyneema-sling. Luckily the screw didn't fail; the climber noticed that something was wrong when the flange became loose slowly. The only duty of the guiding flange is to keep the Dyneema-sling in place on the SpiderJack. The load has to be taken by the lower Carabiner of course. There is no danger when the Dyneema-Kit is used correctly; with the ring clipped into the climbers central Carabiner!

To avoid such operating errors in the future, we ask you to have a careful look at the attached diagram, which is also a part of the users manual of the SpiderJack 2.1.
