If you've had no choice but to store your boards on the floor, then this rack is exactly what you need for your tower. The slim, sleek, polished rack is made with aircraft-grade aluminum. Comes with EPDM rubber inserts that work with an industry-leading bungee to hold boards securely. The forks offer 2.25" spacing on the top for your surfboard and 1.25" of bottom space for a wakeboard. A twist of the knob allows for easy removal. Rigid design will not rattle once installed. Small clamp fits 1-7/8" and 2" tubing; large clamp fits 2-1/4" and 2-3/8" tubing.
