Our Keepa Roof Jack is to be used in conjunction with bathroom fans, range hoods or where ever exhaust vent protection is needed for a ducted system. The Keepa Roof Jack is an excellent choice for venting out air from a ducted system is because of the aerodynamic shape and louvered design. It allows for maximum air to flow while elevating back pressure. Engineered to prohibit insects or vermin from entering the duct, the Keepa Roof Jack is also engineered to stop rain or snow from entering in all US climate zones. The Keepa's standard 11 in. collar height is great for low slope membrane roofs that need ducted exhaust ventilation. These vents have an all-aluminum construction, which means they are durable, lightweight and Will Not Rust. The Keepa Vent is UL tested and certified to meet or exceed most building code standards including California Fire Code. The Keepa Roof Jack tail pipe (adapter) is approximately 2 inches in length and is corrugated on the bottom to fit existing duct work, which makes for a quick and easy installation. Also, the head of the Keepa Roof Jack is removable, which also makes the vents installation on to the roof fast and easy adding membrane/ roofing material over the base flange and collar.
