US longboard fin boxes

The Bahne brothers are legends, and we’ve been proud to sell their boxes and fins for over 40 years. The Fins Unlimited 10.5″ fin box is still as good as ever – never fails and always there as an industry standard for which 90% of longboard fins are made. In 6.5″ 8.25″ 10.5″ and 15″ sizes, there’s a Fins Unlimited box to suit every board, SUP or paddleboard produced.
