🔳 Maurice Franklin Louver-3" Round White Polypropylene Plastic Louver with Insect Screen System (4-Pack). Item #3" PLW-100 Review

I bought these to cover the inlets and outlets in our oven. They seem to restrict airflow causing the oven to not work properly.

Were needed for under seat deflectors which could get wet and smelly due to lack of ventilation. It's really awesome! Boot 3 pack but you only need 1 as you get 4 in 1 pack.

These 3" fans are easy to install. The only problem was that I used a 3" hole saw and some of them didn't fit the holes exactly and fell out. I think it's best to use a 2 7/8" hole saw.

Just what I needed to get airflow to my rubber bag that I used for the worm basket. They ensure good airflow with no problems with insects getting into the bin. My red snakes are fine.

Installed it on the ceiling of our screened in porch. I used a brand new 3 inch hole saw and had no problems with the lovers fitting. Nice and tidy with just enough edges to hide any sharp edges left by the bat. In my case the ceiling was finished off with 1/4" thick plywood so some splinters appeared when the hole saw initially cut into the wood.
