The Builders Edge 12" X 18" Rectangular (Net Free Venting Area: 49 sq in. ) provides added architectural detail with their wood grain finish and sharp distinctive characteristics. Installation is easy with our wide nailing flange, leveling lines, and adjustable stop gauge. Our patented snap-on trim ring hides rough cuts and reduces installation time, while providing a finished appearance once the vent has been installed. Our vents utilize a double baffle design that blocks a direct view into the home and provides added protection against wind-driven rain and snow. The sealed-in fiberglass screen offers complete insect and animal protection. Each gable vent has more venting area than industry standards. Available in 24 colors and a paintable option.
