Wes,
If you are referring to the aluminum angle stock, I used that back in
1960 when constructing a amplifier. I did not think I "invented" it,
and at that time I did not have a drill press, just a hand drill and a
tap, so the holes were not precisely spaced. It worked well, and
complied with the TVI problem of that time (put everything in a shielded
box).

But they *do* allow you to join two enclosure planes while also
supporting a PCB or other hardware. That was the intent of the design.
