I needed a vent cover to replace the old one on outside wall of my house for the bathroom exhaust fans. I had a large wasps nest in my old one so wanted one with a screen. This one was perfect. Not only the right size but looks awesome. Most were just plain white. This one is a nice looking gray and the screws are hidden. I did put a little glue on the screen just to make sure it stays in place but I am very pleased. It looks great on the house and will prevent insects from getting in. I don’t think this would work well for a dryer vent because of the lint that may clog up the screen.

No issues. Fit fine.
