Converts your Seek Air 5’9 or 6’2 into a stable learn-to-wing board. ​Simply drop the Fin Adaptor into the mast track. Secure using the screws and washers supplied with your Seek Air Board. The fin slides into the fin slot on the adaptor. ... We recommend using the DropBox Fin Adaptor set-up along with the two removable side fins for maximum performance and stability from your Seek Air when learning how to wing. You can use your board with the DropBox Fin Adaptor only (without the side fins) for stand-up paddling.
