I have a first floor oval stackhead for a wall register in the
bathroom. I used a set of calipers to get the internal dimensions of
the oval, which measures about 2 in. X 6 1/2 in.
I need to re-route that particular duct in the basement because the
original installation was sloppy and gets in the way of the soffit and
ceiling I'm biulding.
I will use an oval-to-round 90 degree boot as part of a basement
finishing project--to replace a sloppy, twisting run of 5 in. diameter
round duct. However, no local stores carry oval boots.
Looking on line I find 90-degree boots (oval to round) listed in sizes
ranging from 5 in, to 6 in, to 7 in. The dimensions of the ovals are
not listed--only what I assume to be the round sizes.
Does anyone having experience with oval sizes know which 90-degree
boot would match the 2 in. X 6 1/2 in. oval?
