Free: duct 6" Side Takeoff (Oak Harbor)

Brand-new 6" duct side takeoff.
Not terribly square, that's how they shipped it to me.
I have flattened some of the round corrugations to fit my duct, but that doesn't affect how it fits much.
I was able to find a more-correct stick-on version of this, which I used instead.
This is the 6" round-to-square transition only; the fan & filter pics are provided only to show how I was intending to use it.
No, it's not a grow operation ;) Contactless porch pickup in Oak Harbor.
