Ordering Information: This is a Your Crawl Space product and must be ordered separately from all other non-Your Crawl Space products. The listed price does not include shipping. YCS will confirm your order, including shipping costs, and invoice you directly. To avoid delays in order fulfillment, do not send payment to GHS. Flood Flaps® Multi-Purpose Series vents are FEMA compliant flood vents certified to provide flood protection and air ventilation. These models are perfectly designed for an enclosure or crawlspace in a flood plain that desires natural air while still providing efficient flood relief when necessary. The patented grill remains closed and secure until forced open by flood waters, allowing water to enter or exit the enclosed area. These automatic foundation flood vents are also FEMA/NFIP compliant.
