The Skedco 4:1 Rescue 100 Feet Kit utilizes the Rescue Hauler, a double pulley, two large steel ‘D’ carabiners, the required amount of 1/2″ PMI static kernmantle rescue rope, and a handy rope bag with a pocket for storing the pre-rigged system. It can be attached to an anchor and ready to use in seconds. When ordering your Skedco 4:1 Rescue Kit, remember that the rope length is determined by using 4 times the distance from the tripod anchors to the bottom of the hole, plus 30 feet for tying knots, etc. Custom sizes can be fabricated on request.
