5-Inch 125mm

Hvac contractor here. I used two of these to vent a customer's portable ac he used to cool his converted garage office space. Best of all, the covers are easily removable for cleaning. They just snap in place.

I was quite surprised when I received this as it looks and feels fantastic. I noticed others saying the rubber gasket doesnt fit, but it does if you stretch it out a bit. I added a small line of superglue just to keep it in place and worked fine. Install was simple and the screws provided are of good quality and didnt strip. Also, I have no problem with my vent door closing fully. I do have a block under it from my previous vent, so perhaps that is angled slightly? I bought two more and would certainly recommend this to anyone. Great item at a great price.

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.

The supplier was fine, the product was correct and the deliverly was on time.

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 replacement flap is solid quality and very easy to install. It fit perfectly and replaced our old broken one without any issues. Looks great and functions just like new. Exactly what we needed for a quick fix.

Arrived quickly is very good Construction

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.
