The RNA Swamp Ape Spider Leg Sling helps balance limbs during arborist rigging so sections can be lowered more horizontally. It attaches to the rigging line with a Klemheist or 6 to 8 coil Prusik hitch and then clove hitches to the limb being removed. Built from 1/2 inch Swamp Ape cordage, it has a 1,200 lbf working load limit and 12,000 lbf average tensile strength.
