The Fly High Pro X Series Crossbar Tower was designed using polished stainless steel for its two inch, 14 gage tubular frame. Its solid pull locks in tight when being used, yet folds down and stores low and easy. Its mounting bases, under plates, adjustable arm braces, along with its unmatched stiffness, makes it strong, user and boat friendly. The Crossbar allows you to store wakeboards, skis, kneeboards, wake skates, etc... This universal tower is the best all around this year, including its rolls, curves, lines, and looks. 2" diameter tubing. Includes black board pads.
