If you draw a nice diagram with measurements you can have a custom duct
fitting made at a sheet metal shop or maybe an air conditioning contractor.

Does anyone know if there is such a thing as rectangular flex ducting?
I am installing an over-the-range microwave and its vent slot does not
line up with the one currently in place through my cupboard. Since the
cupboard is wider than the microwave, I need to go about 6" over with
my rectangular duct through the cupboard. I figure the best way to do
this would be with flex ducting, or by cutting a straight duct at an
angle and fitting it. Anyone have any ideas?
