Take a look at the Slingshot Hover Glide Tuttle connector with S2AS!

The Slingshot Tuttle connector is an integrated tittle base designed for Deep Tuttle boxes which provides strength and eliminates any movement. This design comes with an integrated base flange that transfers loads over a larger area of the board, which means it is possible to use with another foil with an existing board. Unlike others, the Tuttle Connector from Slingshot comes reinforced, which means it will happily handle the load of foiling.
