4-Inch External Extractor Wall Vent Cushioned Non Return Flap

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.

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.

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.

Yes overall it works great. The gasket that came with it does not fit at all. I did not need it where I installed it. It is built decent quality.

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

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.

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 installed this pretty much right away, as the old one desperately needed replaced (it was most likely 50 years old or more). It was no longer closing properly and allowing moisture into my dryer when not in use, and I even found a surprise dead rodent in the hose at one point! The gasket on this vent will of course fall off unless the piece is tightened to the exterior of the building, so be sure to have it properly seated before securing the vent damper with the provided screws. These holes even aligned with the old anchor points, so it was an absolute breeze. There are tension springs on the duct end, so your hard ductwork should snap on securely (don't use the paper foil or plastic hose for dryer vents, but the flexible hose that is not paper - often called rigiflex - should also snap on correctly). The damper swings freely but is inclined to be closed when not in use. To be sure moisture and critters are very discouraged from coming in, I also put a damper on the inside of the house opposite the outside vent.

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

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

Works very well, looks very good. Way better than cheap plastic that fails quickly.

Excelente calidad de materiales y acabado, únicamente viene desprendido un seguro donde atora el ducto.
