Tuttle ConnectorTuttle Connector Integrated tuttle base designed for Deep Tuttle boxes provides maximum strength and elimination of movement. Designed with an integrated base flange that transfers loads over a larger area of the board, not just the tuttle box. This feature is critical if you expect to use a foil with an existing board. A regular tuttle box is not reinforced to handle the loads of foiling. *M10 Tuttle Adapter Hardware not included.
