The ART Spiderjack 2.1 Dyneema is designed for use with two carabiners not unlike the Hitch Climber set-up. This configuration helps to facilitate easy transitions and changing of anchor points. The Dyneema sling replaces the Velcro attachment on the original ART Spiderjack.

The sling is kept in place with the milled alloy 'keeper'. The sling includes a stitched-in stainless steel ring rated at 12kN. This new version of the ART Spiderjack also has a longer lever with deeper fairleads and an artificial 'roller' or half-pulley for easier rope-tail management.
