Third picture is simple 1 X 1/4" bar stock welded together with some holes drilled in it.
Fourth is 2" conduit lengths attached to some (brazed on) sheet metal channels, that you can find in the drywall section along with the metal studs. The channel allows you to blow out any crud that falls into those conduits, without taking it all down.
