The tree mast stands 32” high and is a made from a 7/8" solid aluminum.  It is available in  thumbscrew and track (Cisco, Bert's, Traxstech compatible) mounting options. 
By mounting our tree masts to a thumbscrew or track base you have the    option of simply turning the unit 180° when you are done fishing.  We    make it easy to do this so that the rod holder tubes can safely stay    inside the dimensions of the boat to ensure that nothing can snag them    when docking the boat.  You can find our safe and secure Sure-Stop  Track   in our online shop!
