Combine crawl-space access and foundation ventilation in one purpose-built assembly. This 18-inch by 24-inch Vulcan access vent is designed for an 18-inch by 24-inch cutout and provides 177 square inches of NFVA. The vented access format allows future entry for inspection and maintenance while supporting everyday airflow and the wildfire-conscious protection associated with the Vulcan vent family. It is a practical upgrade for crawl-space openings where a conventional access door would leave ventilation needs unresolved. Confirm the exterior face dimensions, opening condition, latch or fastener arrangement, finish and local code requirements before ordering. Reinforced packaging is recommended to protect the access door and frame during shipment.
