Kupo 20" C-Stand Riser Column (Black) is identical to the ones that come with the Master C-Stands with Turtle Base. C-Stands get their sizing from the length of their riser sections. The 20” double riser for instance, has two (double riser) telescoping risers and one main section for a total of 90”. Add the height of the base and you arrive at your maximum height, 2 risers, 3 sections (Dia.: 35mm, 30mm, 25mm)
