Shipping Details

Round mini louvers are primarily designed to fill bird block ventilation holes in wood rafters. Round mini louvers provide air flow in to the attic while preventing large insects and small birds from entering. They are easy to install by lightly tapping in. The installation avoids damage to painted areas from vapor and frost. Mini louvers can help protect against intrusion of burning embers through the ventilation openings.

Used to prevent attic access for birds or large insect while maximizing intake airflow to the attic

Shop for it elsewhere.

Would Not Recommend

Unreasonably expensive ($3.25) for something that costs only pennies to make. Cheap construction.

Works as expected. Size not entirely accurate.****

Would Recommend

4.5" is the outside diameter including the flange. Being aluminum, these are quite pliable. Not an issue for me. That said, the inside diameter was roughly 4". I ended up using a 4" hole saw to create the openings in my soffit. There are three "nubs" located equidistantly around the circumference of the inside flange that helps to lock the vent into the soffit. Personally, I added an 1/8" bead of white silicone to help adhere them to the soffit for peace of mind. All in all, it is a good product...
