Review: Works well, item as described, satisfied customer. - I used this to attach the 6” side to a wall cap and the 8” side to 8” flex duct. It worked perfectly and feels very well made, nice and solid. I would recommend.
Review: Super great quality, really a thing of beauty and all I expected was a reducer - I just needed a reducer fitting and wasn't expecting much. I have gotten a lot of off kilter cheap sheet metal fittings over the years and didn't have high hopes for this. It was absolutely perfect, you don't have to be an aficionado of manufacturing to really enjoy this level of quality but I am a real nerd for industrial beauty. Keep up the good work....

### ⭐⭐⭐⭐ Great duct reducer. Worked perfectly.
*by T***T on April 22, 2019*

This was purchased to use on our new range hood that had an 8" opening. Our existing duct was only a 6" so this was needed to connect the two. It worked perfectly. The quality of this item seems to be higher than adapters I've seen in my local stores so I expect it to last at least 20 yrs. Whoever made this one actually takes pride in their work. Shipping was very fast from the west coast to FL. The item arrived earlier than expected. Great seller!
