With the RAM Tough-Track, flat surface mounting possibilities are nearly endless for ATVs, cars, combines, motorboats, tractors, trucks and more. The extruded aluminum version of the RAM Tough-Track can be drilled to any flat surface and is designed for use with #8 screws for easy installation hardware not included. Made to be a dependable and rugged mounting solution, the anodized aluminum provides a smooth slide across the track and anti-corrosion protection. The RAM-TRACK-EXA-17U features 17" of usable track length (aluminum portion), while the included top loading end caps add about 1.5" in length to each end (3" of additional length). Using the end caps allows for two installation options: either use both top loading end caps to create insertion points on both ends of the track, or use one top loading end cap and close the opposite end with the included flush end cap. The Extruded Aluminum Tough-Track is compatible with the RAM Center Loader and 90 Degree Connector , as well as a wide variety of RAM track bases to attach devices like action cameras, fishing rods, phones and tablets.
