4 inch Louvered Exterior Exhaust Air Vent Cover Cap

HVAC materials. Outdoor Exhaust Cap with Fine Mesh Screen. Water deflector plate on the bottom of the vent cover. The air outlet airflow is directed away from the external wall, making the wall less prone to discoloration. Simply insert the vent hose into the louvered vent cover, then mount it on the wall. Easy to remove and clean. Three retaining rings at the socket of the air vent cover prevent falling off.
