Review: Great product - Works great
Review: Durable vent cover - 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.

## Features

- FITS STANDARD 8"H × 16"W FOUNDATION OPENINGS — Cover dimensions are 10"H × 18"W, overlapping your opening on all sides. Mounts flat to the exterior foundation wall — does not insert into the opening. Measure your rough opening before ordering.
- SOLID SEAL — NO AIRFLOW, NO OPENINGS — Completely solid with no louvers, no mesh screen, and no ventilation of any kind. Designed for crawl space encapsulation and conditioning — permanently blocking outdoor air, moisture, and humidity from entering through foundation vents.
- EXTERIOR SURFACE MOUNT — NO CRAWL SPACE ENTRY NEEDED — Attaches to the outside of your foundation wall directly over the existing vent opening — no need to remove the old vent or enter the crawl space. Secure with construction adhesive, Tapcon screws, or both for a weatherproof hold.
- RUST-FREE UV-STABILIZED ABS PLASTIC — One solid piece that won't rust, rot, or warp from years of weather exposure at ground level. Paintable with any plastic-adherent paint to match your foundation or siding color.
- CRAWL SPACE SPECIALISTS SINCE 1996 — Nearly 30 years focused exclusively on crawl space products. Available in Black and White and two sizes — check our storefront for the full vent cover lineup. Our Virginia Beach team is here to help before and after your purchase.

### ⭐⭐⭐⭐⭐ Great product

Works great

### ⭐⭐⭐⭐⭐ Durable vent cover

### ⭐⭐⭐⭐⭐ Exactly what I needed
*by M***S on October 5, 2016*

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.
