The T-4 collapsible tower has a sleek, swoop style for good looks and it folds down in minutes to about 14″, usually lower than the windshield. It is constructed with high strength 2″ 6063 seamless extruded aluminum tube. It is a very easy tower to install, usually about a 2 hour job. The laser cut side flanges have pre-drilled holes to bolt on the R5 wakeboard racks. This method eliminates the need for big, expensive clamps and gives the tower a clean, all one piece look.
