All Exhaust Cap products are made of the highest quality materials and construction to ensure longevity in their intended venting application.

The Rain Cap is best suited for low-velocity or intake applications where a backdraft is not a concern. The conical top is sized and spaced to prevent precipitation from entering the vent opening while maximizing airflow.

The Weather Cap is ideally suited for medium to high velocity exhaust applications where airflow restriction is a concern as well as backdraft. The butterfly damper opens quickly and easily with the onset of airflow and closes again to block precipitation when not in use.

The Velocity Stack is recommended for high velocity exhaust applications where airflow restriction is a primary concern. The outer shell is sized so to be able to collect precipitation and direct it away from the vent opening without blocking the airway.

All Rain Caps are manufactured according to standard industry specifications (SMACNA). Cap diameter is standard 2x pipe diameter with 1/2 pipe diameter vent spacing and angle-reinforced legs.
