While not of the same grade, a pair of the KV drawer rails from Lowes
will come out closer to this than you might think. And slightly torqued
against each other there will be near zero play, and for $15 or less for
immediate purchase. Remove the outer rail of the 3 rail slides though,
then cut the size and section you need.

Metal electrical boxes are good for volume and right angles. Have to
bend things slightly to get 90 degrees, but once there and bolted to
other things they're relatively sturdy. Remove all the hole plugs and
they're relatively light for how good they are too.
