HWG 4" Outdoor Dryer Vent Cover – Stainless Steel Wall Vent Hood with Gravity Flap – Weatherproof Exterior Exhaust Fan Cover for Home & Commercial Use – Pest & Draft Protection

The gasket is 1/4" thick while the cavity is 1/2" deep. Odd until you realize the gasket has a cavity designed for inserting the metal frame (not set inside the cavity). Its a bit tricky to get it to stay in place - once you do, suggest leaving it overnight so it'll stretch a bit. I used gorilla glue in the cavity, then held the rubber in place with 4 large binder clamps until it adhered to the metal edge. Installing over a flat surface it fine, but over bricks, planks, etc., the provided gasket worthless - just get some 5/8" thick rubber and fill that cavity or silicone it in place. The vent itself is rugged and it fits VERY snugly inside a 4" duct. If it's too snug to enter the duct (a problem I had), flatten the 3 holding clips a little. A ring of silicone sealant inside the duct prior to inserting the vent provides a better exhaust seal and eases installation. I also filled teh 1/2" cavity with silicone to firmly seal the vent to the duct. This will force the exhaust air through the port, avoiding moisture build-up against the wall.

Great item better than the plastic one needed to be replaced Use a small vacuum to clean out the area

Well made and strong.

Overall, a good buy for the money. Seems sturdy and fairly easy to install. It has a foam gasket around the damper. A rubber one would be better as it think it would last longer. I wish the outer flange was flat rather than the rectangular one with the rubber gasket. The screw holes need to be larger diameter as I mounted it to a concrete slab and had to drill the holes out to use concrete screws. Would buy again.

Fit what’s perfect . easy to install.

I measured my old one that I wanted to replace and being a silly old lady, I measured the length and width of the cover - 6”. After it arrived and I saw how huge it was, I realized I was supposed to measure the round pipe it that it’s meant to cover. Ok, so I sent it back to Amazon and sent my son to a very popular home improvement store to get one there. He came home with the right size, but it was the flimsiest and cheapest piece of crap vent, it has sharp edges on it and was little more than aluminum foil. So brought that back and re-ordered this one in the 4” size from Amazon. Arrived today. Quality is unbelievable. Sturdy, no sharp edges, finished off nicely, heavy, solid, made exceptionally well and will last another 50 years. And, it was less expensive than the flimsy one! Five stars.

The rubber seal that interfaces between the vent's outer edge and the house sheathing did not fit well at all. It was too small, required a lot of stretching and kept pulling off the vent's edges. Not a big deal, I used Tite Seal as flashing which is a metalized flashing with a sticky butyl rubber backing. This provided a supple watertight seal. I add two diagonally crisscrossed 1/4"x1/4" galvanized wire mesh screens to the backside for bird, mouse, and bug control(see pics). Finally, I added an 8" long 6" galvanized round vent pipe with a female to female termination to the back of the vent. This pipe was screwed and silicon caulked to the vent side for a robust air/watertight seal. This pipe extension allowed me to easily connect the male end of the microwave hood vent pipe to the other side of my interior finished wall. Because I am using this for a over the stove microwave vent I found it difficult to locate an 8"x8" vinyl block so I added a J channel picture frame around the vent. Even with these modifications I'm extremely happy with the vent because it's built like a tank.

Great size and easy to install

Ce n'est pas la première fois que j'en achète,vu mon métier de cuisiniste, et je suis toujours satisfait. Beaucoup moins cher que dans un magasin de bricolage.

Por ahora están aguantando bien, ha superado un buen temporal de viento y agua y sigue. La tapa la conserva, lo que si ha volado es la junta de esponja que viene de fábrica. El agua no ha conseguido entrar. Como recomendación, no está de más antes de instalarla sustituir la junta de espuma que trae, por otra de goma que quede bien fijada. Con eso evitas que se pierda y te haga ruidos después. No veo óxido.

Bra produkt, kändes som väldigt bra kvalité, enkel att installera. Dock saknade jag en lite lätt fjäder att trycka tillbaka locket när ingen luft strömmar ut. Annars var jag nöjd med den i helhet.

Well made and solid. Looks good in place of the original plastic louvred cowl.internal flap rubber edged for quiet closure. Can recommend.

sehr einfache Montage, Lamelle macht keinen Lärm beim zurückklappen. Empfehlenswert
