[John Dirks Jr]

What do you call the boxes that the flex ducts connect to? I keep thinking distribution trunk. Is that correct?

I have always referred to it as the main trunk line.

Hmm. Well the main trunk is steel and comes up into the attic. From there a larger flex duct carries airflow to this box which has two smaller distribution lines feeding rooms.

So, its part of the distribution system but I think main trunk for this part is not as specific as one could get.

I would use distribution box. Those are ready made so you might find an HVAC supplier with on line catalog for something more impressive.

I've always used: "Ductboard Distribution Box"

They are made out of "ductboard" and they "distribute" ...

Like JL noted ... some company may have a fancier name in their catalog.

And there's plenum more where that came from. []
