The CSC0 Carbon Fiber Short Center Column from Benro replaces the standard center column on Benro carbon fiber 0 series tripods. Using a short column allows you to take full advantage of the widest leg angle on these units, so that the tripod can reach its minimum height. The column features a standard 3/8"-16 thread for mounting most tripod heads.
