The TetherTube was modeled after the popular AR Tube Rod Holder and works flawlessly with spinning and casting rods. The angled lead-in at the top of the TetherTube makes it a breeze to insert your rods and helps lock in your casting and spinning reels keeping them aligned and ready. For added security, the integrated but easily removable hook and tether systems ensure your rods stay put if things go wrong. Caged attachment points on both sides of the tube offer multiple hook points, and the oversized hook design is sized to attach directly to the shaft of your fishing rod if desired. The Tether Tube is compatible with the BlackPak Pro but will not work with the classic BlackPak. Made from marine grade polymers, the Tether Tube is built to last and comes with our Built for Life Guarantee. The included hardware kit allows for installs on the BlackPak Pro or applications where a nut and washer are needed.
