calimaeroHWG 4" Dryer Vent Cover Outdoor Walls - Cowled External Extractor Fan Vent Dryer Cover - Robust and Weatherproof Stainless Steel Outdoor Dryer Vent Cover - Fits Only with Metal Pipes

Very nice quality to replace my old plastic one.

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.

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.

As others have stated, the gasket is almost pointless because it's sized as such so as to have to stretch it into place along the back edge of the vent cover. I've experienced this before with another cover and this time decided to throw them in the trash and simply and neatly caulk around the edges and screw heads with clear silicone.The unit itself, however, is much better than the 3 or 4-flap design this company also sells. The single flap is just the right weight and has remedied our LG dryer's "D80" flow sense error. Going to mask and paint it black to match the external house gutters and trim.

Great replacement for the plastic vent, which was falling apart after only a few years.Easy to install, even though getting the rubber gasket in place took a bit of an effort.

The vent is well made and works perfectly. It was easy to replace the old vent with this one.

Yeah, this is a solid vent cover. Finish is outstanding and the item comes with screws and rubber gasket.

This vent cover is good quality and sturdy. The flap seals completely when the vent fan is off. However, the rubber seal that contacts the house does not fit well on the flange on the back of the vent cover and did not work for my installations. An alternative is to cut pieces of wood to fit inside the back of the vent cover and use adhesive caulk to seal against the house. In my installations, I also cut pieces of wood to extend the cedar siding under the vent cover.
