Drainable Blade Louvers - EDD-401

Model EDD-401 is an extruded aluminum stationary drainable louver that protects air intake and exhaust openings in exterior walls. The drainable head and stationary horizontal dual-drainable blades collect and further channel water to the vertical downspouts located in the louver jambs where gravity takes effect, allowing water to escape at the louver sill.
