FCS II Surfboard Fin Boxes 0 o 3o 5o 9 o Efficient keyless system for quick fin installation and release. The FCS II system requires no grub screws or keys to secure the fins to the board. Fins can be easily inserted and removed in seconds, allowing you to adapt your equipment to the conditions, on land and in the water. Recessed leading edge with flush base connection improves water flow. These features not only create a sturdy anchorage to the board, but minimize water disruption through a more flush and seamless transition between the fin and board surface. The FCS II System is backwards compatible with all your favorite FCS dual tab Fins. Constructed using a corrosion resistant titanium tension rod, and a rotating, wear-resistant polymer barrel. When the fin is inserted into the plug the barrel interacts with a groove detail in the fin to lock it into place using a combination of downward and lateral force.Lightweight Composite Frame encapsulated by high density foam reduces weight and maintains flex. Center - 1 plug (Box) only Side Set - 2 plugs (Boxes) (left and right - only sold as a pair no singles)
