This super-duty rod holder offers maximum positioning of your fishing rod. Lifts and rotates every 18 degrees/20 positions for maximum all-around positioning. One-handed adjust-ability by pulling the tube sideways and then moving it to next set of teeth and releasing for full engagement and strength of all 20 teeth machined in the side of this holder. There are 6 positions from 0 degrees to 90 degrees and one position past 90 degrees to get the rod tip to the water if desired. We have machined a center hub to prevent lifting when used with Dipsy Divers on the bottom and side sections. This is an aluminum machined rod holder you will not be disappointed with its strength and flexibility.
