This kit comes with a Rod Holder II and a SidePort Tracloader. Having two styles of t-bolts, this fits on most aluminum boat tracks as well as kayak tracks. The Rod Holder II is compatible with baitcasting, spinning, offshore, and fly reels so it'll accept just about any fishing rod you might have. Installation is simple and makes mounting accessories easy. This mounting base will also fit any of the accessories in the RAILBLAZA StarPort assortment, not just the included Rod Holder.
