The KV-3-TP is the 3 inch Diameter Commercial Keepa Roof Jack with a 3 inch inner diameter and 7 inch tall collar. In addition, it also has a 2 inch tailpipe that can be used for duct ventilation. It's ideal for ventilating bathroom fans and range hoods. It allows for maximum airflow while alleviating back pressure.
The Keepa Roof Jack will stop insects and wildlife from entering the duct. It will also prevent rain or snow from entering inside in all climate zones. The Keepa’s tall 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 tailpipe is approximately 2 inches long and is corrugated at the bottom to fit existing ductwork. 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.
The vent head is removable therefore allowing easy installation on EPDM, TPO or PVC roofs. In addition, this attic vent is compatible with membrane roofs.
In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. Most importantly, the Keepa Roof Jack comes in an array of sizes with an optional curb mount flange for additional clearance or flat flange flashing.
