Never Used!! Includes Complete assembled mast foot with Universal joint, base plate, joint saver. The UXT Extensions are fully integrated with stainless steel cleat/pulley bottom assemblies offering the best weight to stiffness ratio and creating very light but also very strong extensions. The weight has been reduced by eliminating all unnecessary plastic while increasing the cross- section of stainless steel parts for increased strength.This part can now withstand over 900kg of downhaul load twice as much as used on the largest racing sails. The special geometry with tilt bottom pulley makes perfect sail pulley/rope alignment. This allows the sail to be down hauled all the way down (block-to-block) and it reduces down hauling friction. Weight: 0,65 kg
