A neat way of tidying up excess US fin slots and Mini Tuttle boxes (if you have removed a set of Quad front fins to sail as a Twinser).
Please ask if you require a fin screw/nut for the 130mm US Blanking plate,

Note. Mini Tuttle and Power boxes do alter in size so the K4 head is made to fit the largest and may need rubbing down to fit slightly smaller boxes.
