Gibraltar Building Products 2.375-in x 2.375-in Silver Aluminum Soffit Vent

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.
