Longboard Fin Box – 10.5″ (Black)
A fin box is used in the construction of Longboards, Mal’s or Retro Shortboards.
They enable you to have a larger box fin on your surfboard. And not only will it create a stronger hold (will not get pulled out easily), it enables you to adjust where you put your fin. This will have an effect on how the board surfs; fin nearer the back is more stable, fin nearer the front makes it looser.
