Original Futures Finbox 3/4 inch for the front side fins of a thruster, quad, 5-fin or 2+1 setup. The box is 3/4 inch (1.905 cm) deep.
Futures is proud to build one of the lightest and strongest fin systems in the world! The proven full-base system now features Interwoven Laminate Technology (ILT). These cutouts in the flange create an even stronger bond with the laminate of the board by getting the resin between the surfboard and the fiberglass laminate.
