Amazon CustomerAmazon Customer: I installed these to ventilate a storage area under my porch. I think they will do a good job and keep the rain out. And they look cool.

Laketime: These things are so nice that if I had known when I built the house I would run the vents out the front just to show them off. Seriously, they are very nice and durable. I put clear silicone adhesive sealant on the back lip of the vent to hold it firm but there are two holes for screws if you application will allow it.

Jason: Watch the sharp edges on the inside edge. Wow did I cut my finger just taking the wrapping off. Have not installed yet waiting to heal first.

Harley Dixon: After reading all the reviews, I thought I would be getting a poorly formed object that would require me to wear heavy duty gloves to keep from cutting myself. And that it would be considerably undersized. Having done duct work all my life, I WAS prepared!

BUT...

What I received was a very wll designed and great looking air vent. ALL the exposed edges that one would encounter when installing were properly rolled and NOT the least bit sharp or dangerous. However, the INSIDE edges, which one should never have a need to touch, were just as they came out of the machine that made it...quite sharp. But I can see no reason for ever having to stick my hand or finger inside the unit. As I said, ALL the outside edges that will be handled are rolled, not the least able to cut anything and safe.

As far as being undersized, the size you are buying is NOT the size of the unit, but the suize of the duct it is to fit in. I replaced a plastic vent in my 4" duct, and this nw vent fit perfectly. It requiired me to press it fairly tightly into the duct, and the little tabs grabbed the side of the duct just as they should.

A duct's stated size is the outside diameter...4...

Robert: BEWARE! Vents are razor sharp! They will cut. Also the you’ll need tape to secure the vent hose as it’s a bit on the small size for 4” duct. Over all much nicer than the plastic one we used to have.

S.L.: These things are OK. I bought one and liked it enough for my application that I bought two more.

I'm using them for engine exhaust outlets on electric generator enclosures. They keep the weather and bugs out while not restricting exhaust flow. When the gasoline engine exhaust has to push on a flap or damper to open it to let the exhaust flow out, that causes back pressure and encourages carbon monoxide build-up in the generator enclosure. That's not a problem with these because they do not restrict the exhaust flow at all.

A four inch flexible pipe and this work great to channel engine exhaust out and away from the generator shelter. I use three "L' brackets with niobium magnets fastened to the semi-flexible aluminum pipe to secure the exhaust line to the muffler on the generator. This allows easy detachment to remove the generator from the enclosure for servicing. A line of Loctite red RTV high temperature adhesive sealant around the opening of the pipe that rests on the muffler makes a decent gasket/seal. All this works quite well as long as there's no restriction causing back pressure to force exhaust gasses out of the pipe where it joins the muffler. So these are...
