I have the Canadian Version the S.S.E.

Frame cosists of 4 pipes about 1 inch dia.. so that is 3/4 pipe I think.. by 5 1/2 ft long. One end has short pie thread and threads into the top, bottom has longer thread, straight I presume about 2 inches or so, fastens to base with jamb nuts top and bottom.
Computer sits on a shelf about 1/16 steel fits between the pipes with 2 edges bent down at 90. then U bolts fasten this to the frame pipes.
Another by the hose outlet, its about 3/4 angle iron again held by U bolts.

That is the whole frame..
