I would appreciate receiving advise on whether it is fine to connect a
return branch to the end cap of the rectangular trunk on the return
side of the furnace. I know that with regard to the supply side, the
end cap is intended to cause static pressure and therefore no branches
should come off the end cap of the supply trunk.

Thanks in advance for your input.

Cheers, John

To answer your question, yes, you can connect to the end cap of a return
plenum. But, if you have two, then the air *may* not return equally in two
ducts of the same size.

The reasoning behind the notion of *not* taking a branch / trunk run from
the end cap of a supply plenum is to prevent favortism from the blower. If
on the other hand the length of the plenum is 3 times the girth, then in all
likely hood you can. But generally you are correct in *not* taking a branch
/ truck off the end cap.
