iPower18-Inch Square Aluminum Automatic Gravity Shutter Louver Vent, Silver,2-Pack

I replaced plastic vent louvers which did not last at all. I suppose that between wear and heat (we live in central Florida), that the plastic just gave out and flaps just began falling out! The balance might be a little better for the power of my attic fan as the louvers don’t seem to open far enough.

We bought two of these as self closing and opening vents for my wife's greenhouse. They work perfectly.. Very well made. Highly recommend.

Installed on the side of my house for the attics vent. Satisfied with quality!

Just what I need for my greenhouse. They work well and are fairly priced.

Easy instsll

Louvers work perfect. Great product good price definitely recommend.

This works fine. My only complaint is it doesn't seal very well. I am using it in my wood shop to exhaust lacquer fumes and sawdust and the small gaps around the sides will allow bugs to enter. I probably need a much bigger opening that I could add a screen to but that is not an option in a rented shop and a screen in my small opening blocks too much air flow. Other than that it is great.

Very heavy build the only thing I question is if vent fan has enough muscle to actually open vents. As far as built they seem very well built with thicker materials than I expected, these are not cheap built louvers . I know doubt will buy again when I need more....

Installed easy enough and opened when the fan came on, closed when it went off.
