Round Back Roof Jack with Curb Mount Flange | RBV-4-C4-CMF-TP<\/h3>\n

The RBV-4-C4-CMF-TP is a 4 inch roof jack for duct ventilation on top of a roof curb. This vent has a 4 inch inner diameter, 4 inch tall collar, and a 2 inch tailpipe with a curb mount flange. The curb mount flange allows for installation on a roof curb on flat roofs<\/a> to provide additional clearance.<\/p>\n

All 4 inch roof jacks come with a standard 7.5 x 7.5 inch curb mount flange.<\/p>\n

Installation<\/strong>: The Curb Mount Flange will only fit over a\u00a0Roof Curb<\/a> with a 7 inch outer diameter.<\/h4>\n

This 4 inch roof jack is engineered with a curb mount flange which is to be installed on top of a roof curb. In other words, this flange will only fit over roof curbs or an existing base with a 7 inch diameter. As a result, this gives the vent head extra clearance allowing for installation in all climate zones<\/a>.<\/p>\n

AVP's 4 inch roof jacks are compatible with the\u00a06 inch tall<\/a>\u00a0and\u00a012 inch tall roof curbs.<\/a><\/p>\n

This roof jack is mainly for ventilating bathroom fans and range hoods. It allows for maximum airflow while alleviating back pressure.<\/p>\n

How it Operates:<\/strong><\/h4>\n

The inner louver design prevents insects and wildlife from entering the duct. It also prevents rain or snow from entering. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. It can also be painted to match the color<\/a>\u00a0of the asphalt shingles.<\/p>\n

This Round Back Roof Jack with Curb Mount Flange has an all-aluminum construction. To clarify, this means they are durable, lightweight, and will not rust.<\/p>\n
