Zigco SpinRx Fishing Anchor Pulley Libro La Guerra de los Mundos De Wells, Herbert George Buscalibre Chile. The Zigco SpinRx Fishing Anchor Pulley eliminates anchor rope twisting while still providing a 2 to 1 mechanical lifting advantage of a pulley. Built to make life on the water a little easier, the SpinRx is a better anchoring solution for boaters and anglers. Combines a pulley and a swiveling clevis into a sleek, low profile solution giving you the mechanical advantages of a pulley without the frustrations of rope twisting. Two sealed ball bearings allow the anchor to spin independently of the anchor rope. Constructed with aerospace grade aluminum and hard anodized for corrosion and wear resistance. Stainless steel hardware for increased corrosion resistance makes this a suitable pulley for both fresh and saltwater anchor systems. Attachment and removal are quick and easy. Remove the split ring and clevis pin, insert pulley around the rope and reassemble. The anchor can be attached directly to the SpinRx by securing both the shoulder bolt and lock nut. Fully tighten shoulder bolt and nylon lock nut using a 7 16" wrench and 5 32" Allen key. Or for quick anchor attachment, a locking carabiner can be added to the bolt. Made in Bozeman, Montana, USA.
