Strengthen eave ventilation with a Vulcan reverse-tab vent sized for nominal 2x8 rafter bays at 24 inches on center. The 7.5-inch by 22-inch galvanized-steel assembly provides 119 square inches of NFVA and combines ember-resistant screening with a heat-reactive matrix designed to help reduce ember and flame intrusion. Its reverse-tab configuration supports a streamlined installation in compatible eave assemblies while preserving strong airflow. This vent is appropriate for wildfire-conscious construction and selected replacement projects. Field-verify the framing, opening dimensions, required NFVA and fastening detail before ordering, and follow the manufacturer’s installation instructions for sealing around the assembly.
