Aluminum Roof Cap Exhaust

The Imperial 4-in Aluminum Roof Exhaust Cap helps to remove humidity from the exhaust area, limiting moisture that can cause damage to your home. It features a sturdy aluminum construction that resists corrosion, and a damper to stop outside elements from entering the vent. Use it to effectively exhaust kitchen and bath fans through the roof. This exhaust cap is not intended for clothes dryer venting.
