RAILBLAZA 12" SlimLine Track allows for versatile mounting of many of your externally mounted paddling and fishing accessories while limiting the number of holes you need to drill into your boat. The 12" design allows you to add up to 3 accessory bases, 4" long each. This means instead of drilling up to 12 holes in your boat to install 3 accessories, you can now install the RAILBLAZA 12" SlimLine Track with just a few mounting points and switch out an unlimited number of accessories or bases when needed. The track's unique design features 2 small gutters on the underside, which allows for epoxy mounting with self-tapping screws when no inside access is available. The slightly concave-shaped back of the track allows for a solid mount to flat surfaces as well as surfaces with slight contours. The track is constructed of a lightweight PVC and polycarbonate composition for strength and UV protection. Its flat-black, non-glare color is excellent for use when in hunting situations for minimal to no glare reflection. Manufacturer model #: TRK12-RB.
