Mast Top Tuttle Box head suitable for Kite Racing Boards 

Note. This adaptor is not to be used in a Windsurf Foil box

Most kite race boards use a tapered, drop-in box connection—specifically the Tuttle box—to lock high-performance hydrofoil masts or race fins securely into carbon composite race boards. This standard eliminates wobble, reduces hydrodynamic drag at high speeds compared to track or plate mounts, and delivers instant rider feedback. A flange has been added around the base of the head to better spread the load through the structure of the board.

Supplied with 2 -  M6 x 50mm Torx bolts to attach the head to the foil mast .
