4-Inch 100mm

Really well designed and built. Went on with ease. Works as expected. Bonus: well sound insulated so wind gusts don’t bang the flapper audibly. Mounted in high wind area.

High quality product! The vent cover replaced the old plastic one perfectly.

This was impressive right out of the box - the packing itself I would add was really tough box offering max protection Once installed, the clean lines and Stainless finish looks very classy on the exterior wall. I understand why some might have been frustrated with the rubber gasket, which is slightly smaller than the frame: however I personally think this was a positive thing. TIP: a little bit of SuperGlue on the corners was enough to secure it firmly in place. Then you can easily snug it up tight against the wall for a tight seal. The Flapper on mine fit well and moved freely; and when held off-axis slightly you could see it seal nicely - the gasket is a bonus here, to dampen any banging! When mounted however it did hang ever so slightly open - this is more a factor of the wall's true verticality though. Perhaps a suggestion for the manufacturer is to recognize that many will have this issue - if it was designed with a built-in internal angle of only a few degrees it would solve this without any negative impact on the functionality. The only other thing I found was the mounting screws were too short for me - Mine had to go through the Dryvit Stucco into the plywood sheathing, so with the thickness of the vent itself (which is nearly an inch) I needed 2-1/2" screws. It would be a bonus if the manufacturer could supply a few different lengths to accommodate different wall thicknesses. Very pleased though, an incredible value I would say.

I needed a wall vent for my over-the-range extractor, and I was awfully disappointed by both the selection and pricing at my local big box retailers. I’m glad I opted for this one, as it’s far nicer in both build quality and appearance than anything on the shelves. The stainless steel looks and feels great, and the flap operates silently and effectively. It’s made to last, strong, sturdy, and stable. I have a few nits to pick, but I’d certainly buy this again despite these complaints. First, the gasket - as others report, it’s a PIA to get on. As I have very rough stucco siding, I opted to use sealant in concert with the gasket. This made a huge mess when the gasket decided to slip off mid-install. Words were said. Bad words. Words my neighbors shouldn’t have to hear enunciated so clearly and powerfully. A better gasket might alleviate this - or better yet, a flange (or optional flanged model). I ended up fixing the gasket to the vent with some sealant, waiting a day for it to cure, then proceeding with the install - I recommend this method if you’re planning to use sealant. The screws were short for my application as well. I don’t mind, as stucco isn’t a great substrate anyway. I picked up some stainless machine screws, washers, and nuts locally, and essentially bolted it in place instead. It feels very secure this way. Finally, this fits INSIDE a 6” vent pipe. I’m not sure how big of a deal that is, but ideally, you’d have each piece fitting inside the next in the direction of flow. That way, air doesn’t escape the intended path to the area around the tubing. I suppose with the gasket, there’s probably not much place for air to go, but I’d still much prefer this fit OVER the 6” vent in accordance with the rest of the system. All told, I’m still very impressed with the build and performance of this little vent cap. It’s better, cheaper, and much nicer looking than anything else I could find.

That is a beautiful external extractor particularly the dumper works great I installed it to my basement fan and it worked perfectly

Fits as advertised

The material is shiny, claim to be stainless steel. This is great because this metal color can be combined with any wall color in general, avoiding painting or matching the wall color need. Comes with a rubber packer that helps to seal gaps between the wall and the vent hood. It has a flapper that opens easily with the air blowing to outside and close by gravity when there is no air blowing out ( if you want it close properly, it has to be place perfectly vertical or a bit upward angle. Down side for me, it doesn’t come with a mesh to prevent animals to get into the vent. I bought a stainless steel mesh sheet and cutout a circle from it to place it just behind the flapper as second containment. My flapper stay a bit opens since appears that my wall is not perfectly vertical, so the mesh will be an insurance. Overall, I recommend it.

This stainless steel vent looks like it’s well made, but there’s one major problem and one thing that I find going to cause problems in the future. The first thing wrong is the gasket is about a quarter inch to small both directions. It doesn’t fit unless you really stretch it. It kept jumping off. I finally had to super glue it in place to get it to stay so I could install it in my wall. The second thing is the mesh to keep out vermin is probably not small enough to keep out mice and it is welded in place. No way to clean out the vent with out totally taking it out of the wall. It would have been easy to make it a separate piece that could be removed and still keep out rodents.

I’m very happy with great quality and design with these vent covers — they fit perfectly and look clean and modern. The material feels sturdy, and installation was quick and easy. They improved both the appearance and airflow in the room. Excellent value for the price — I’d definitely recommend them for anyone upgrading their vents.

Excelente, ningun problema con la instalacion

As described. Fits well and works.

Buen material para mi le unieran puesto una malla para impedir el acceso a los insectos aparte de la puerta que tiene pero esta bien la pieza

Look it's a dryer vent! But.. it's not plastic! Which is what drew me to it. Plastic is all they seem to sell at the big box stores for a little less money than this and they are mostly junk. With the severe heat in the Ontario summers and severe cold in the winters it doesn't take long for the plastic to become brittle. Product came well packaged and Installation was fairly easy. I attached it to 4 inch rigid dryer vent pipe. The rubber gasket to prevent noise was a bit of pain, had to stretch it to fit and it would pop off fairly easily. However, once the vent was secured to the wall the gasket wasn't going anywhere. No need for glue like some people have mentioned. Used Tapcons to attach to wall and an exterior sealant to make it water tight. I’m not sure this vent will offer a ton of protection from mice as the flap if fairly light. However that's easily rectified if it becomes an issue. Tested it out and the exhaust comes out just fine, flap opens and closes as expected. So far I am satisfied with this purchase. Lost one star due to annoying gasket, but other then that its a good product.
