The "Ultra Protect" basement window well covers are designed with "Safety" & "Security" for your home and family in mind. These versatile basement window well covers are manufactured using virtually indestructible clear polycarbonate plastic riveted to a continuous structural grade aluminum angle rear support. These basement window well covers will support a minimum of 250 lbs when properly installed using our patented SAF-T Locking System that is included with each "Ultra Protect" window well cover. Installing these basement window well covers over your basement window wells minimizes the risk of persons falling into deep, uncovered, unprotected basement window wells, preventing possible injury. The model RT536 (53 in. x 37 in.) basement window well cover is designed for use over Rectangular shaped Egress basement window wells. Its versatility makes it possible to be installed and trimmed to the profile of any type (steel, plastic, brick, wood tie, concrete etc.) basement window wells also known as "Area Walls". Once installed it can be trimmed to the profile (plus up to a 1 in. overhang around the perimeter) of the window well openings using an ordinary jigsaw with an aluminum cutting blade (10 to 14 teeth per in. blade for best results)to make for a perfect fit window well cover. A patented, solid steel locking system with pull pin release quickly unlocks the basement window well covers (without the use of a tool, required by code) from inside the basement window well.

Rated 4.6 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Window well cover I would recommend this window cover. I purchased the thinner, cheaper kind for a previous house and hated those. These are very durable and come with all hardware needed. My only concern is that none of their sizes were exact fits for my wells. I had to get a little creative to get it to work. Please note that I did not use the included hardware. Nonetheless, I am very pleased that winter hasn't penetrated the covers (even with 70 mph winds last weekend and 12' of snow that fells in the days preceeding that. Good stuff. December 22, 2008
Rated 4.0 out of 5.0 by Overall good product This fit my egress window well almost perfectly. Instructions were good, delivery was fast. The one thing I marked them down for is not including both lengths of u-bolts, if you want to install them the more secure way, you have to cut them short yourself (after installing the nuts on them). I am less than 250 pounds, but I didn't really want to test the strength of this...I'm confident kids and pets won't fall in, and that's what matters, in addition to keeping trash (both wind-blown and deliberate!) out.

Rated 5.0 out of 5.0 by Dyne Window Well Cover The window well is sturdy, was easy to install and provides added security (locking pins on the inside) to the basement window. We like the fact that it is flat (vs. the typical bubble type) and that it holds up to 250 pounds. It arrived within a week of ordering it from the Home Depot web site and we were happy that we did not have to wait a long time for it to arrive. June 16, 2006
Rated 4.0 out of 5.0 by I ordered three window well covers and someone only sent two. Not sure who is at fault for not sending all three. Was suppose to fit my window well but did not and will have to be modified. August 1, 2012
Rated 5.0 out of 5.0 by low profile - nice appearance Great - as described. Good quality and a good value. I would buy again. August 5, 2013
