Dual tab FCS II & I type fins to Usbox adaptor for Longboards or Stand Up Paddle boards with Usbox Central thruster finbox to be able to accept Dual tab FCS type fins
Regarding adaptor appropriate fitment it has to be counted that tolerance is +/- 5% over the finbox dimensions, so in some cases a light sanding needed with 220grant sandpaper over a flat surface.
Handling and care
Surf fins due to their super light construction (in comparison with windsurf fin rtm technology) are much more sensitive when they get in contact with the shore or the rocks. An extra care needs to be taken to avoid damages or total distraction of the fins or the board. We don’t take responsibility for any fin loss or damage in your board.
