Give a larger attic opening strong ventilation and a more integrated finish with this 22-inch by 30-inch Vulcan gable vent. The galvanized-steel assembly provides 262 square inches of NFVA and uses a middle flange recessed 1-5/16 inches for compatible wall and cladding details. Ember-resistant screening and a heat-reactive matrix are designed to help reduce ember and flame intrusion while allowing everyday airflow. Its substantial size makes it a strong fit for gable-wall applications where fewer, larger vents are preferred. Confirm the exact rough opening, wall thickness, cladding interface, finish and required NFVA before ordering. Use rigid, reinforced packaging to protect the face and flange in transit.
