Small Outward Mounted Crawl Space Vent Cover 10" H × 18" W — Solid ABS Plastic, Surface Mount, Seals Foundation Vents for Encapsulated & Conditioned Crawl Spaces | Crawl Space Door Systems (Black)

Works great

Thus vent cover was made of hard durable plastic. It fit inside the hole in my foundation vent perfectly! The price is little steep for the amount I needed, so I only purchased one for now. You can install this cover with screws or with glue. I was happy with it overall.

These covers are perfect for what I need. I purchased this house two years ago and for the past two winters, rain kept getting inside the garage through the vents. After much frustration, I decided to make sure this winter will be different. I thought about having a contractor just seal up the vents and stucco over it but then I thought this is going to cost quite a bit. After a lot of researching, I found these covers. They attach right over the opening with a strong construction adhesive. Before installing, I primed and painted them to match the house color and now you can't even notice them. This is a good and inexpensive fix to an annoying problem. I highly recommend them.

The vent covers fit perfectly, but I wish there had been some pre-drilled holes.

I like the ease of installing this, it looks good and works well

These are massively overpriced for a cheap brittle piece of plastic. They’re also not sized large enough…I have the correct sized vents these are made for but they don’t overlap the foundation enough to mount them with screws so I’m having to rig them in place with adhesive and caulk.

I bought these to use in the winter to cover my crawl space vents underneath my 1940’s home. I used black gorilla duct tape to attach them to the house and removed them after the last freeze. They looked decent with the tape, but I made sure to keep the tape square and neat. I wish there was another way to attach and remove more easily (maybe I’m just unaware). I was able to cut a couple of them using my reciprocating saw, that I needed to fit around some wiring and also some that I needed to remove the lip because the vents are low to the ground on one side of my home. Worked great for what I wanted them for. The seller was great and answered all my questions quickly.

Excellent…covers my engineered flood vents and stops water from coming in….
