The Model ACL is a heavy duty Extruded Aluminum Combination Louver/Damper. It is designed to protect the air intake or exhaust openings in the exterior walls of any building from rain and weather while still providing efficient airflow. The Drainable Blade design provides the BEST PROTECTION against water entering the opening by channeling water away from the blades and down the jambs. This eliminates water cascading from blade to blade. The adjustable rear blades allow for tight shutoff of the opening when needed.
