The Round Back Roof Jack with Curb Mount Flange is used for ventilating bathroom fans or other duct applications. The curb mount flange is designed to fit on top of roof curbs on flat roofs. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. It allows for maximum air to flow while alleviating back pressure. Most importantly, it comes in an array of sizes with an optional flat flange for sloped roofs.

The Round Back Roof Jack with Curb Mount Flange is engineered to stop insects and wildlife from entering the duct. It is also designed to prevent rain or snow from entering. These vents have an all-aluminum construction. To clarify, this means they are durable, lightweight, and will not rust.

The tailpipe is 2 inches long and is corrugated at the bottom to fit existing ductwork. This allows for a quick and easy installation.

AVP now offers 6 inch tall roof curbs are available as well as 12 inch tall roof curbs.
