Non-standard Rangehood duct?

Looking for a non-standard? rangehood duct that goes from 10"x3.75" to a 4" round at a 90degree angle.

At HomeDepot there is something similar that goes to a 6"round and there is a 6" to 4" reducer available, but the cabinet depth is too shallow.

HD also has a 10" x 3.75" to 4" round STRAIGHT fitting to which I could attach a 90degree 4"round, but not enough height in cabinet to do that either.

Is such a duct fitting available anywhere or would a sheet metal guy be able to knock one out for me fairly easily?

duct work

Any good tin bender can just make you one up. Why do you want to cut it down to a 4" ?????? A vent fan with a 3 1/4" X10" should have a 6" round vent pipe. You could also put a 3 1/4"x10" stack on the fan, cap it and cut the 4" round out the side of it. or there is the 3 1/4"X10" boot 90 d you could use amd put a 4" reducer in it or cap it and come out with the 4" pipe????????

HVAC Supply House came through

Thanks for the advice. I did find a supply house in Chicago that had the "4 x 10 90 to a 4" round boot" as a stock item. Then he crimped the 4" round for me in about a minute at no extra charge.

Ed, I know the rangehood should duct to a 6" round, but had to go with what I had coming out of the wall. There was too much going on in the raceway to accommodate a 6" duct. Good suggestion on the stack and coming out the side. But when the stock item was available, hey, gotta go for it!

Thanks for your prompt replies guys.
