Smart Vent Dual Function, Engineered Foundation Flood Vent, FEMA Compliant and ICC-ES Certified Model 1540-510… (Stainless Steel)

Grossly overpriced but having them be dual purpose is a plus. & the inspector liked them. All that matters I suppose, please the big man

These were recommended by a friend who use to be a building inspector. I installed two which was code required on my 14x24 shed. On the final inspection the current inspector was very impressed with these and said they would have more then necessary flow unlike the plastic ones he usually sees and has to fail based on inadequate flow. I was just glad to pass the inspection. These were not hard to frame out and install and I can always close them off inside right over the framing I put in. If you gotta install flow throughs these are the best.

This is exactly what I wanted and need. Most importantly it works!!! Closes under 40 degrees temp and will work in an emergency

Good quality, and easy to install!

Best flood vent on the market, but expensive. The combination vent/flood vent means less vents you need to install overall. Stainless is forever, install and done.

It lowered my flood insurance and keeps the wind from blowing under the house (crawl space). I am very pleased.

Cost efficient and easy to install

2 of the vents were missing the installation straps.
