The FCS II (FCS2) surfboard fin box system is a strong and high-performance fin box system. An extremely tough pre-glass fin box installation that makes a tight foam-to-foam connection for optimal torsion strength.
Simple installation of your FCS II fins without the need for screws or tools. An aerospace grade titanium spring loaded rod locks the fin base into the fin box which improves surfing performance by transferring energy from the surfer's pressure on the board straight to the fin without any delay. The FCS II fin box is also compatible with FCS dual tab fins using 2 grub screws. FCS II filler kits assist filling the gap if that is a concern for the user.
