for stands: weld a vertical tube down from the rail, then take a piece of sheetmetal (rather thick) and weld a bigger diameter tube under 90° on the sheetmetal.
for use: put down the sheetmetal with the tube and insert your rail
and for transport: take it apart and you have a very clean rail to transport...
