Smart Vent Dual Function Foundation Flood Vent combines flood protection and ventilation in a single, durable stainless steel unit. The bi-directional design lets water flow freely in and out to relieve hydrostatic pressure, while patented internal floats unlatch and allow the door to rotate open during flooding. Each vent provides up to 200 sq. ft. of flood protection per ICC-ES/ FEMA acceptance and supports continuous airflow for crawlspaces and enclosed areas. The insulated model offers the same flood coverage with an insulated core for garages and air-conditioned spaces. Constructed from T316L marine-grade stainless steel and 100% made in the United States, the vent is corrosion resistant and built for long-term performance. Rough opening: 16 inches x 8 inches; weight: 2.336 kilograms. Packaging: frustration-free packaging.
