Draft Blocker - 10'' Inch Backdraft Damper Duct - Draft Stopper - Backflow Preventer - Inline Fan Vent - Vent Deflector (10'' Inch)

My new range hood

Weak and flimsy. Expected a sturdier piece.

I put this in my basement to exhaust my server equipment heat out the window. Well now it's down in the 40° range outside and it's actually too cold for me. The damper definitely works no cold air seeping inside. However the damper has to be installed 9:00 and 3:00 not 12 and 6:00

fast shipping, good product

I ordered two of these from the same seller. They both are wrapped in a cardboard sleeve. One was shipped in a box but the other sent in a plastic envelope. WTF??!Guess which one came warped and damaged?This is a criticism of the seller/shipper. The intact product seems very nice and fits securely within the HVAC duct. The flaps will open with the slightest breeze (one way) and stay firmly closed against a foam seal on any backdraft. I am so very pleased with the one unit that arrived undamaged that I am ordering a replacement for the damaged one from the same seller while sending the damaged one back.The product: highly recommend.The seller: mmm, we'll see.

Does exactly what it says and did the job well. I’m really happy with this purchase.I used it to stop the clanging in the vent above my oven - on windy days, the flaps above the vent motor would make a banging noise. This seems to have completely eliminated it.You’ll notice I used a bit of foam to create a tight seal; my roof vent pipe was a very odd 10.75” in diameter, so I got the 10” unit and added the padding. Works great!

Nothing to not like. Works great

Installed this when replacing my downdraft gas cooking top. Installed in a vertical position, it works very well. Almost entirely eliminates all backdraft in the cold season. Good price and sturdy.
