 and frame in a box inside of the opening of the siding because they said that it was a couple inches on each side of the hole before they got to the studs on the side. So I said, just frame out a box that fits inside there. You have to do it piece by piece and screw them in one at a time. Stick some insulation behind it so it's insulated all around the outside of this hole. And then have those 2x4s hang over into the opening about half of the thickness of the 2x4s, so about three quarters of an inch.
