Threlaco39'' x 16'' UV Resistant Polycarbonate Window Well Cover Egress Window Covers for Winter Basement Window Well Covers Outside for Courtyard Balcony Exterior, Clear

I bought one and I was skeptical as this material tends to be expensive when it is thicker and large areas. It was so good, I bought 2 more to cover all 3 well basement holes. It is sturdy, comes with a sticky film that protects it. It has a bend instead of 2 pieces glued together. Nothing compared to the flimsy plastic covers. This is heavy duty. It comes with self taping screws that did their job on the metal sheets that make the wells.Don't hesitate.

No directions included with product. The information and packaging included fasteners (the description says screws but there is no screwdriver slot) and did not indicate what kind of screws they were. They look like self-drilling screws but no indication whether they are masonry or metal-or both. The sales site shows two crews into masonry and three in the window well metal. The center screw in the window well looks like it has a metal clip attached to it. The "screws" need a wrench or socket to tighten.It would be more convenient to have window well clips to make the unit removable if there is a need to do so.Directions do not give the size hole necessary to fit the fasteners. Directions also do not indicate if a special drill bit is needed for drilling the polycarbonate material, which is a strong material. Here is what I found on Google: "You can use an ordinary iron drill or HSS (high speed steel) drill bit to drill holes in polycarbonate. Position the drill perpendicular to the polycarbonate and run the drill at medium speed immediately. Don't use too much pressure but let the drill do the work. It's important to use a drill that is not brand new but is still sharp." and " they can be easily cut and drilled without worrying about having previous experience. Cutting solid polycarbonate sheets is also easier than cutting acyclic."The overall look is sleek and clean, which is appealing. I also like the strong polycarbonate material.

Loved the easy installation and clean appearance however the clips to attach the cover to the window wells were not included. Had to order separately.

Happy to find these!! Easy to install 👌
