Muddycreek Tackle Dual Tree Rod Holder tubes are removable, which is great for storage purposes. The rod tubes are produced with right-hand threads, so you can unscrew them quickly when needed. An O-Ring on the threads absorbs vibration to keep the tube from coming loose. Muddycreek states it fabricates the rod holders out of a heavier tubing than other manufacturers do. Since the ends are fully machined, rubber caps are not needed. The choice of Dual Horizontal Tree rod holder tubes includes one with a standard mount assembly, one with a track mount, and one with a standard gimbal mount with a 30-degree angle.
