Naw, those are just ducts for the flexible ducting that will go to each light, two
intakes on each side, two exhausts, although that does sound like a good ideal if I didn't already have the setup planned out. A "box" with 2 intakes connect to the the tops of the exhaust ducts in the attic; this "box", which I made from 1/2" sheet insulation, contains the fan and on the opposite side from the intakes on the box is the exhaust duct that goes to another exhaust "box" that empties into my living room [room exhaust also empties into this final exhaust "box"].
'Will post a closeup later today.
