Duotone EPX RDM Cup - No Extension
Sometimes your mast is exactly the length you need it to be, and adding a normal windsurfing extension adds to much length even when it is set as short as it will go. This is when the Duotone EPX Cup stubby extension comes in handy. It actually has no extension (and no adjustments), but you do get 3 pulleys and a cleat so you can rig your sail with ease. Fits into any RDM (reduced diameter) mast and works with euro-pin style mast feet.
