Conflicting Information

"Built in screen to prevent insect entry (Must be removed if using for Dryer Venting)" is in the description then the tech says "You can't remove it without professional assistance." Well which is it? I want critters to stay out but want to use for a dryer. Can't the screen just be made so it is removable? Once a month remove, rinse and reinstall. That's how my current one is but it is on the roof. I am trying to keep from having to climb up onto my roof once a month. This is unnecessarily dangerous and i want to be able to clean my vent while on the ground. Nice and safe.

The screen can probably be cut out ok if you have the right tools. You would need something that can cut the metal screen (looks to be stainless steel?) close to is perimeter, maybe some small angled wire cutters.

How to use as dryer vent at end wall

When used to vent dryer to outside home wall: how can critters be prevented from entering while avoiding lint buildup?
Asked by: kimfit
Dryer vents need to be cleaned now and then anyway to keep any possibility of fires but the interior screen will prevent rodents and the flap will prevent insects from entering.

how do you remove the insect entry screen

Asked by: matt
From what we could see there are two possibilities, both tricky. The first would be to carefully cut the mesh with a pair of wire cutters (end-cutting). cut around the circle from inside the pipe side as closely as possible to the sides. bend the remaining stubs outward so they don't catch lint. The second is to slit the mesh into several pie-shaped quadrants and remove them with needle-nosed pliers using a rotating motion to wrap and pull the sections. We did not try either and it did not look easy as the mesh is firmly clamped by the collar.

What are the dimensions of the vent frame?

4 in is the diameter of vent pipe. The exterior of my hour is stucco and the cut-out rectangular opening for the dryer vent is five and 3/4 in. by six in.
Asked by: buster
The vent we purchased is 6 1/2" wide x 7 1/4" tall overall. It is designed to sit flush against the outside of your building utilizing a hole large enough to pass a 4" pipe (4 1/4"- 4 1/2" diameter). It can be secured by screws through the flange or high quality adhesive caulking under the flange, or ideally both.

The "flap" works well. I Drilled a hole through my wall, and it installed fine. However, the pipe portion is not long enough to reach through even a 2x4 thick wall. I had hoped to be able to hook the elbow on the inside of the wall directly to the wall vent. However, it is short enough, I had to get a straight pipe extension to attach to this vent to extend inside the interior of the house so I could then attach the elbow connection on the inside. I would probably not buy this again, and find one with a longer pipe.

Rated 5 out of 5 by from Bathroom exhaust fan I bought this vent hood to use for a termination for a bathroom exhaust fan that I recently installed. After reading the reviews, you have to question some of the negative reviews and the experience of the people giving the negative reviews. The vent hood works excellent. I had no problems installing it, of course I used the right tools for the job. I tested it and the vent hood does exactly what its suppose to do. Now, could you go out and buy a top of the line vent hood, absoulutley but you will pay the price. Believe me, If you purchase this vent hood you will have no problems.

Got tired of replacing the cheap vinyl louvered vents and started searching for something more durable. Theses aluminum vents should last indefinitely but I wasn't crazy about the mill finish so I primed and then painted them white. Here's the really good new...these vents have a damper rather than louvers. The damper opens more easily and the bathroom fan now moves WAY more air than it ever did. What an improvement. The second vent was for the dryer which had no problem opening the old louvers, but I'm guessing it works better for moving the lint.

This seems to be pretty well constructed and like the fact it has a bug screen and foam padding to keep the flapper from making a lot of noise when the wind blows. Install was easy, had a tough time installing a 4" insulated hose of the pipe, but after making a small cut in the pipe with tin snipes I was able to slide the hose over it. There wasn't any holes drilled in mine, I drilled three across the top and three down each side, I know over kill but don't want any leaks.

It will serve it's purpose but it is manufactured from very thin and flimsy aluminum sheet metal. Avoid mowing the lawn near it. I was expecting something more sturdy and robust especially at a price point of $23-out-the-door. Having buyers remorse and should have opted for a more solid galvanized steel model...live and learn!

This is the best gosh darn 4" round wall vent that IO have ever installed! The cool shine of the all aluminum body, they easy motion of its flap, the even grid of its screen, and a full 8.5 inches of exhaust area. If you are in need of a totally superior, solid metal, 4" round wall vent then this baby is for you.
