Macklanburg Duncan makes these aluminum extrusions and should be readily
available through most lumber yards and box stores.

That was already suggested to him a week ago... no bite. Odd, that,
because MD makes a whole line of very standardized extrusions you've been
able to buy since the early 1960's with no changes in the line.
