Default Furnace return plenum "bangs" when blower motor starts/stops

That way, you're not ripping clothes when you walk by. Good
idea.

I ended up using aluminum angle iron but mounted it on the
inside so I
got all the stiffness I needed without any protrusions --
all I had to
do was to remove one of the ducts which gave me access to
the interior
of the plenum. I then used sheet metal screws to secure two
horizontal
pieces of angle iron.
