FCS II (FCS2) Premium Surfboard Fin Box Side Fins are sold as sets of two (1 left, 1 right) Available in White or Black The FCS II Premium (FCS2) surfboard fin box system is the strongest and highest performing fin box on the market to day. Simple pre-glass fin box installation makes a tight foam-to-foam connection for optimal torsion strength that just might be the difference between continuing your session after a collision with something or having to replace your fin box. When paired with fins from the new FCS II Essential Series Fins, it’s now possible to install and remove your fins in seconds, without the need for any 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 from a looser fin box to fin connection, like a glass-on fin.
