The "Ultra Protect" basement window well covers are designed with "Safety" and "Security" for your home and family in mind. These professional grade lightweight basement window well covers are built using clear impact resistant, UV-resistant, polycarbonate sheet plastic and structural grade aluminum. Installing an "Ultra Protect" basement window well cover over your open basement window well minimizes the risk of persons or animals falling into deep, uncovered, unprotected basement window wells, preventing possible serious injury. When properly installed using our solid steel “SAF-T Lock” locking system (included) these covers will support a minimum of 250 lbs. This locking system features a pull pin release that quickly unlocks the cover from inside the basement window well without the use of a tool (required by building codes) making for a quick and easy exit in the event of an emergency. The model SR500 (48 in. x 23 in. semi-round) window well cover is designed for use over typical corrugated steel window wells. After installation this cover can be trimmed (if needed) to the profile (plus up to a 1 in. overhang around the perimeter) of any type basement window well (steel, concrete, block, timber etc.) by using an ordinary jigsaw equipped with an aluminum cutting blade (8 to 12 teeth per in. blade for best results) making for a perfect fit window well cover over any type window well.

Rated 4.6 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by Excellent window well cover This window well cover looks good and has a clever locking mechanism. However, the lock is not one that would prevent an intruder with a small saw from getting to the window. Installation was not difficult. However, the instructions were on the skimpy side, For instance, I had to figure out for myself that the bolt holding the lock in place goes from the inside out with the nut on the outside of the window well. In addition, it is important to be sure that the lock bracket is close to flush with the top of the window well. Otherwise, the locking bolt may not be long enough to allow you to insert the pin into the hole through the bottom of the bolt. September 23, 2014
Rated 4.0 out of 5.0 Very easy to install. I probably would not put 3 kids and a dog on to test. Performs well and allows light into basement. May 28, 2006
Rated 5.0 out of 5.0 by Looks & functions great Likes that it lays flat, is non-obtrusive & attractive (no colors to conflict with home paint, etc.) Does job as intended. While instructions indicate installing lots of brackets, ours fit nicely under well & siding cavities without brackets. Wind doesn't move. April 29, 2014
Rated 5.0 out of 5.0 by Well made,arrived on time and cost effective I had a difficult time in locating this item as the window well was not built to normal specs. The sales rep at Home Depot was very helpful in helping me to locate this item and it had arrived at my home on exactly the day that I was told delivery would be made. Have had nothing but good experiences with Home Depot in all of my past projects,keep up the good work! December 28, 2011
Rated 5.0 out of 5.0 by Window Well 48 in. x 23 in. The window well cover is just what I need for my window well. June 25, 2011
Rated 3.0 out of 5.0 by Prepare to spend time on installation I received the window cover within a week. No problem with the delivery. However, once I opened the package and saw the installation kit, I had to return the package to nearby Home Depot. I did not like the installation process. The material is OK. If you have time and know how, then the product is recommended. . August 21, 2010
