The 2 in. round soffit vent 12-pack is an easy-to-install option for intake airflow. These mini louvers will provide critical intake ventilation in hard-to-ventilate or restricted areas. The flange of the vent allows for an easy and secure installation without the risk of falling out. While on the other hand, most other mini louvers fall out over time. Soffit vents control moisture and rotting problems common to eave and overhang areas by providing needed intake airflow for exhaust vents. In addition, they also help provide proper temperature balance and energy performance.The 2 in. round soffit vent is constructed of durable, corrosion-resistant aluminum and is powder-coated white. Additionally, each mini louver has a screen inside to prevent insects from entering. When paired with proper exhaust ventilation, the round soffit vent will allow for optimal airflow.
