Super Slant with an open escape hatch 2

Custom Super Slant Window Well Covers

Our Super Slant window well cover is custom-made to fit your basement window well, with a steeper slope than our other custom covers to keep rain, snow, and leaves off the top of the cover and away from your basement window.

  • Extra Slope for Optimal Drainage
  • Welded Rust-Free Aluminum Support
  • Mesh Sides Provide Constant Air Flow
  • Quick-Release Lock System on Egress-sized Covers
  • Flip Top is Hinged with Prop-Up Bar for Easy Access
  • Escape Hatch is Available for an Additional Cost on egress-sized covers

High-Quality Super Slant Window Well Covers

The Super Slant is designed to fit nearly any window well, no matter what it’s made of, and has a hinged flip top that is made from UV-treated polycarbonate that stays clear for more than 20 years. On non-egress-size covers, the hinged flip top is standard, or for larger covers, we design the cover with a hinged escape hatch for IRC code compliance.

Every Super Slant ships fully assembled and installs in an afternoon. We can substitute the standard aluminum mesh sides for solid polycarbonate sides at no extra cost. In climates with blowing snow, removable polycarbonate inserts are an excellent accessory to keep out the weather. On most sizes, we can powder coat the aluminum framework so the cover blends beautifully with your home’s existing color scheme. Basement ventilation is easy–just open the window.

Why Choose A Super Slant Cover?

The Super Slant has the best features of all our covers rolled into one. It has a steeper slope than any other cover that Window Well Experts builds, causing rain, snow, and lightweight debris to shed off the cover. A welded rust-free aluminum frame supports the polycarbonate top, while mesh sides let the window well breathe. Each cover holds 400 pounds of static weight and uses the same UV-treated polycarbonate as our lifetime warranty Sloped and Flat covers, with more than 20 years of outdoor life.

Frequently Asked Questions

The UV-treated polycarbonate top is rated for more than 20 years of outdoor use without yellowing, cracking, or splitting. The welded aluminum frame is rust-free, and both come with a 7-year warranty against material failure under normal use.

Each cover supports 400 pounds of static weight. That handles a heavy snow load, an accidental step, or a fallen tree limb without bending the frame. Super Slant covers aren’t rated as a walking surface, so look at a safety grate if you need a load-bearing cover.

Yes. Covers built for an egress-sized basement window well include a hinged flip top and a quick-release lock that opens from inside, keeping the rescue opening clear for emergency escape. An optional escape hatch is available at additional cost. Check your local building code before ordering.

There are several factors to consider:

  • Egress Compliance – This is the most important consideration when purchasing a window well. If the basement window is meant for emergency exit, your window well must comply with your local means of egress codes.
  • Aesthetics – Standard corrugated steel wells are a sturdy option, but sometimes you want to improve the view from your basement. We carry decorative wells in egress sizes, and Decorative Liners are an economical way to improve the look of smaller wells.
  • Durability – We proudly offer the best wells on the market. Correct installation and a well-fitting cover will extend the life of your window wells, keep animals and debris out, and most importantly keep snow and rain outside the well where they belong.

We offer a range of egress window wells including white, decorative stone-look, and fiberglass options. We also offer complete code-compliant package deals with our Egress Kits. Egress codes vary at the state and county level. If you have a question about window well sizing requirements to make your basement egress code compliant, please call us.

The aluminum mesh blocks leaves and large debris and keeps air moving through the well, but light rain or fine snow can drift through in heavy weather. Ask about solid polycarbonate sides at no extra charge, or add a removable polycarbonate insert to block snow.

Yes. Because every cover is built to the right size for your well, a Super Slant fits a concrete well as easily as a metal window well. A Super Slant cover purchased for a metal window well will need a firm, level surface, such as timbers or pavers, to rest on. Send us the dimensions, and we’ll quote the cover.

We ship to every state in the continental United States. Shipping rates and timing are calculated at checkout.
