Product Overview

The Adjust-A-Grate Model L9 fits inside window well openings that project from the house 34 - 37 in. and have an opening of 45 - 60 in. along the house (USE INSIDE DIMENSIONS). This adjustable aluminum window well grate works best for METAL OR CONCRETE WELLS WITH ROUNDED FRONT CORNERS. These are NOT RECOMMENDED for RECTANGULAR wells as the first set of "loops" is shorter to accommodate a radial corner. These window well grates fit a variety of well contours and sizes within the range to provide a custom fit at a reasonable cost. This grate is designed to protect your family, animals, and home from the hazards of an open basement window well without having to purchase expensive custom window well covers. This adjustable window well grate is made of tempered aluminum and is strong enough to support up to 400 lb., preventing people, larger animals, and things from falling into the well. Yet, this aluminum window well cover is light enough to allow quick escape in an emergency and has open ventilation to allow natural light and air to flow into the basement window. Made of tempered aluminum, this window well grate won't rust or require painting, doesn't get cloudy or weaken like plastic in the sun's harmful UV rays, and because it allows for ventilation it won't collect dirty water, lawn debris, or dirt that block natural light to the basement.
  • Protects from the hazards of open basement window wells
  • Designed for metal window wells with large radius front corners that measure 45 - 60 in. in length along the house at the back of the well and 34 -37 in. projection from the foundation in the center of the well.
  • Not intended for use on wood, concrete or block rectangular-shaped window wells - front "loops" that run parallel to the house & "supports" running perpendicular to the house are sized to accommodate the curvature of a standard metal well.
  • Adjusts for a custom fit, allowing it to fit a variety of contours on a metal window well with ease
  • Lightweight enough to be moved out of the way in case of an emergency - just lift & push
  • Quick and easy to install with the included hardware and no special tools required
  • High-quality, tempered, maintenance-free, aluminum construction provides strength and durability
  • The design allows up to 90% of natural sunlight to enter the basement window well
  • Provides security as a break-in deterrent (When used with the optional security kit, not included)
  • Supports up to 400 lb. when properly adjusted and installed
  • Installation video and instructions provided with U.S. based customer support
  • In order to determine the correct model of Grate your window well needs, make sure that you are measuring from the concrete foundation out to the window well (inside dimension) and lengthwise along the house - again the inside dimension. Make sure that you measure every well, as there can be different sizes of window wells even on the same house
  • If using this product with casement (crank out) windows ensure that the top of the window is at least 2 inches below the surface of the window well. Anything less indicates the grate would prevent the window from opening in an emergency.

I installed 2 of these adjustable grates over my window wells that are approximately 4 feet deep which would be difficult for a child or small animal to get out of. I also installed the ladders and have the security kits as well but have not put those in yet. Not sure if the 400+ pound weight support capability advertised is realistic but IMO these are a better deal than some other higher priced alternatives available that would have cost significantly more as well as shipping costs.

Great cover for our well windows!
We have been looking at a lot of alternatives for window well covers, many much more expensive. However, these grates work better than we could have hoped. They were not very hard to adjust and when done, look very custom. They sit down in the well just enough and have enough weight that the high winds don't bother them. They also seem very strong. I was able to stand on them and felt secure they would hold. It is nice too, to be able to open the window and not affect the fresh air coming in. I think they will hold up and look good for a long time. Great investment and highly recommended!

A grate solution
This window well cover is a better solution than those plastic covers that become brittle and discolored over time. I have oversized window wells with large basement windows that let in lots of light, so I wanted something that would allow light to pass through. These Adjust-a-Grate covers are a little more pricey, but they are built to last.

Out of all the grates that we looked at this...
Out of all the grates that we looked at this one seemed like the best option at the best price. When it arrived, it didn't disappoint. It is well built and the adjustability on it works well for what we needed. It is heavy duty enough at supporting a 400lb capactity, some of the more expensive options were only rated up to 300 lbs. It allows plenty of light in while at the same time providing a level of privacy due to the reflective nature of it when viewing the window from the outside. Happy with the purchase, I would recommend it and buy it again myself if I had a do-over.

    Superior product, but a real pain to get just right and install. It took me most of a day to install two of them with the security cable. Nonetheless, I wouldn’t trade them for anything.

      Looks great, affordable especially for the do it yourselfer. Very sturdy and looks good as well.. Make sure you measure each window well upon installation or you will be spending more time on adjustments. Would definitely recommend.
