Fin Boxes

Have you ever wondered how much stiffness is lost in a carbon composite surfboard fin when it's mounted to an ABS plastic box?  We use the highest quality laminating epoxy to build our fin boxes.  Notice that there are no flimsy little holes in the sides of our fin boxes to promote mechanical adhesion.  That's because we are building these with a thermal epoxy that will bond, molecularly to your board.  These are the strongest and most responsive fin boxes out, as far as we know.  For their weight: 1/2" - 38 grams, 3/4" - 44 grams, these are the strongest fin boxes out that we know of.
