Protect a common ember entry point without giving up needed airflow. This 4-inch round Vulcan eave vent combines a clean white aluminum face with ember-resistant mesh and a heat-reactive matrix designed to help reduce ember and flame intrusion during wildfire exposure. It fits a standard 4-inch round opening and provides 8 square inches of NFVA, making it a practical option for soffits, eaves and retrofit projects where a discreet finished appearance matters. The compact format is easy to handle and ship. Verify the required vent quantity against the building’s ventilation calculation and confirm substrate, fastening and sealing requirements before installation.
