Our Keepa Roof Jack is to be used in conjunction with a ducted system.
The Keepa Roof Jack is used for ventilating bathroom fans or other duct applications. 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. As a result, this attic vent is suitable for installation in all climate zones. Most importantly, the Keepa Attic Vent comes in an array of sizes with optional curb mount flange for additional clearance.
The Keepa Roof Jack is engineered to stop insects and wildlife from entering the duct. It is also designed to prevent rain or snow from entering in all US climate zones. The Keepa’s standard 11 inch collar height is great for low slope or flat roofs. These vents have an all-aluminum construction. To clarify, this means they are durable, lightweight, and will not rust.
The Roof Jack’s tail pipe is approximately 2 inches long and is corrugated at the bottom to fit existing duct work. This allows for a quick and easy installation. In addition, the head of the Keepa Vent is removable, therefore allowing easy access for maintenance to the duct below.
