Air Louvers 700TL Transom Louvers are designed for installation into hollow metal frames above doors where ventilation between spaces is required. The inverted split Y-blade configuration prevents visibility while allowing airflow, making this model suitable for commercial, institutional, and industrial applications requiring transom ventilation. Heavy-duty welded steel construction provides durability while the flush mounting design allows clean integration into hollow metal framing systems.
