Got a window bench put in, but need a way to direct the air from the old baseboard vent register hole to out the front of the bench. NOt so sure a box store is going to have the proper vent duct parts I need in the correct shape. This guy online makes something exactly for it but it'll cost $72 shipped which is ridiculous: https://toekickductor.com/product/toe-ductor-baseboard-vent-kits/
Any help is appreciated. I'm not so sure I'll be able to cut a vent boot / trim, but maybe.
vent hole is about 14" x 2", register hole in front of bench is about 10" by 4"
