What Makes These Rectangular Covers Different?
UV-treated, unbreakable polycarbonate stops sun damage, so the clear covers are less likely to yellow or split, and the strong light transmission of clear polycarbonate keeps natural light flowing into your lower level. Every rectangular cover uses aluminum components with stainless steel hardware for rust-free, long term durability. Sloped, Flat, Super Slant, and Grate covers safely support up to 400 pounds of static weight, adding a heavy duty layer of protection for your family’s safety.

Frequently Asked Questions
The best cover depends on your window and well. If your window extends above the well, especially a crank-out window, an Atrium Dome is a strong choice because it can be built to whatever height you need. If you need airflow, a Super Slant with mesh sides or an aluminum grate works well, and a Sloped or Flat cover is excellent on any well where a sleek, low profile cover is desired that will help keep out water and debris.
Clear covers help keep rain and debris out of the well, which reduces water pooling that can lead to water infiltration and water damage. Proper drainage inside the well still matters. Aluminum grates are designed for ventilation and safety rather than rain protection.

Kathy and Molly were excellent to work with. Both were very knowledgeable and helpful. I highly recommend them. After pricing our other companies, I found them to be the most cost-effective for my custom covers. So glad I find them. Great existence from beginning to end. The product is very good quality.
