The Vevor foundation flood vent is designed to allow automatic water entry and exit during flooding to help relieve hydrostatic pressure and protect foundation walls. Built from zinc-coated steel with a painted surface, it offers strong corrosion resistance and durable performance. Its removable back plate and net surface make maintenance easier while still helping keep out unwanted critters. This wall-mounted vent is suitable for crawl spaces, garages, and other enclosed areas below the base flood elevation. Installation is straightforward with included mounting hardware.
