Not True 8” and 4” duct size
This duct reducer is not the standard 4” or 8” size. Also received a returned unit based on the return sticker still on it. I would avoid this product if you’re using a standard 8” or 4” ducting

Not what I expected
What I expected what close to 4 x 8 inches. What I got was 4.375 x 7.875. I presume it is close to 4 x 8.
