I know of two manufacturers that do it "upside down". Heights is one and
there is another (can't recall the name) that looks almost like it that is
also upside down. They are aluminum towers and each section is tapered (so
you can't install them the wrong way) and the upper section joins the lower
section by fitting inside of the lower part. It makes a nice funnel for
rain. I have one.
