After finding this vent on Amazon. I ordered 6 of them. When they were delivered. The vents shipped had the same model # on them. But was a total differant vent. The one pictured mounts with a screw at each corner to mount them in the foundation. But the ones sent are for new construction. To be installed as the foundation is laid. I could now use them for my projectWitten Automatic Vnt. 304LGR Automatic Foundation Ventilator This order ended up costing me $28.50
due to shipping charges not being refunded. This was totaly not my fault
That the product was misrepresented in the discription and picture on.

Great product, arrived in good shape, easy to install. They actually automatically close when it gets cold outside. These Vents are used for under a house on pier foundation. We closed it in underneth with Durock pover framing, added vents then stone facade to prevent pipes from freezing. These vents give the required airspace per code. Check with your local code to see how many you need per sf of space.
