It resembles a DIY Flexi done by someone good, and using sleeves over the threaded rod typically used for the columns.
Canuckaudiomart member smally21 has made stuff for me, he is close to Toronto. My custom flexi was something altogether different - a pint sized version 1/2 the normal size. It sits beside my full size flexi, the smaller one is for my dedicated netbook, USB drives, DAC, and power supplies etc.
Good fun!
