Product Description
These units combine drainable exterior louver blades that prevent rain intrusion and damage with adjustable interior dampers that open and close to regulate airflow. They are generally adjusted when installed and left in that configuration permanently. They can be set to allow a specific amount of air to flow in and out of buildings and structures.
