If you have a windsurfing foil with a Tuttle headed mast, this plate will allow you to convert it into a track plate for use with all forms of twin track foil boards. All bolts supplied for the conversion but no plate to board fittings (requires 4 x 6mm Countersunk screws). Head is fitted with an EVA board gasket.

Note. You will need to drill two 8mm holes into the head of your Tuttle mast for the two side bolts  (please do not use without doing this).
