Rated 5.0 out of 5.0 by Great Product! I have an older home with 4 window wells. They had inadequate, homemade covers over them. For safety reasons, I wanted better, sturdier covers that left in light and air. I was skeptical of this product due to the limited reviews. I questioned that since it was adjustable would it really be sturdy enough. I purchased 2 of them to try. I installed them myself over the weekend. The first one took me a while. The instructions tell you to make a template by placing cardboard over the window well and drawing or tracing the outline of the widow well from underneath. The way my window wells are made, it is impossible to get up from underneath. It took me a couple of tries and some time, but eventually, I got it installed. Since I now understood how they worked and what I had to do, the second one installed very quickly. I had some relatives over on the weekend and had some of the men stand on them. They all commented the grates seemed very sturdy. Overall, I'm very happy with the product. They're sturdy, look good, fit well and once you understand how they work, they are easy to install. I'm ordering 2 more for the remaining window wells. I live in a rural area surrounded by woods so I covered them with hardware cloth to help keep the snakes out of the window wells. April 29, 2013
Rated 5.0 out of 5.0 by Solid. Wanted a cover to keep kids from falling in our basement window well, but also wanted light to be able to get through. The unit is very solid and easy to adjust. My window wells are the circular variety and due to the siding installed above, I had to trim off part of the grate to make it fit (not the fault of the grate). Works well and will buy more for our other windows in the future. August 14, 2012
