The Railblaza Accessory Tracks allow for versatile mounting of many of your externally mounted paddling and fishing accessories. Unique design features 2 small gutters on the underside for epoxy mounting with self-tapping screws when theres no inside access. The slightly concave back allows a solid mount to flat surfaces as well as slightly contoured surfaces. Lightweight PVC and polycarbonate construction for strength and UV protection. The nonglare flat black finish works great in hunting situations. Accessories can be easily mounted to the track using the Railblaza Track Nut and Screw Kit (sold separately). Placement of these mounting tracks is variable, ranging from the front or back gunwales of the boat, top or side of milk crates, or the space between the seat back and the deck. Available: 8 The 8 design allows you to add up to 2 accessory bases, 4L each, with minimal drilling. This means instead of drilling up to 8 holes just to install 2 accessories, you can now install the Railblaza 8 Accessory Track with just 3 mounting points and switch out an unlimited number of accessories or bases. 12.5 The 12.5 design lets you add up to 3 accessory bases, 4L each, with minimal drilling. Instead of drilling up to 12 holes in your boat just for a couple accessories, you can now install the Railblaza 12.5 Kayak Track with just 5 mounting points and switch out endless accessories or bases whenever you need.
