Review: Great company, great products - After reading through dozens of reviews and product information, we first bought the AC Infinity Flexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust. It was packaged so well you could send it as a Christmas gift, the quality of the duct tubing was outstanding. Fast forward a week while we were installing the new stove exhaust fan, we realized we would need this flapper piece, as the old one was getting stuck. We were so impressed with the duct tubing that we purchased this product from AC as well, and were not disappointed. It is the Mercedes of exhaust flappers. This AC flapper was the exact size advertised at 5.79" width/diameter, which was just a smidgen smaller than most of the others advertised at 5.90" diameter. So instead of having to monkey around with it, it slipped perfectly inside the Vikio range hood 30" under cabinet kitchen hood with 980 CFM, 3 speed gesture sensing & touch control panel in stainless steel, vent hole on top the hood. A little larger it would not have worked, we are grateful the AC specs are perfect, it made the install a dream come true. I do agree with another review I read, in that the AC 6" ducting is a tight fit on their own product/flapper, although I got it to slip on, it was as tight as could be without being unworkable, but the bottom line is it went on. And it slipped over the existing 6" coupling tube to the roof perfectly. We will keep this company in mind when doing other projects, such as heating, vents, dryer etc, well worth the cost. Thank you
Review: Good quality and works as advertised. - Good quality and works as advertised. I had to saw off some of it to make it shorter so it would fit in my microwaves outside exhaust vent but it works. You can hear it close every time the vent shuts off.
