The RBV-9-C2-TP is the Round Back Roof Jack with a 9 inch inner diameter and 2 inch tall collar. In addition, it also has a 2 inch tailpipe for duct ventilation. It is mainly for ventilating bathroom fans and range hoods. It allows for maximum airflow while alleviating back pressure.
The Roof Jack’s tailpipe is approximately 2 inches long and is corrugated at the bottom to fit existing ductwork. This allows for a quick and easy installation.
The 9 inch Roof Jack is best for ventilating steep slope roofs. The inner louver design will prevent rain or snow from entering.
This static vent is ideal for venting out bathroom fans or range hoods. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. The Round Back Vent is great for residential roof applications because of its low profile.
These vents have an all-aluminum construction. To clarify, this means they are durable, lightweight, and will not rust.
