Note on Freight - As it costs the same to send 1 as 20 masts (you are paying for the volume of the packing tube) the shipping program may give incorrect pricing - continue with your order and we will adjust the freight charge by giving a refund or requesting extra where required.
 Carbon Fibre Mast Tubes come in 1 metre or 500mm lengths with each size fitting into the next size for mast and boom building, eg 12mm fits into 14mm etc. (When fitting carbon tube inside a smaller diameter, fine sand until you get a neat fit. - forcing the smaller tube into the larger tube can result in the tube splitting.)
