This is a 3/8- 13 7/8 x 33 3/4 sheet of Polycarbonate. Often refered to as Lexan and often mistaken for Acrylic or plexiglass.
The only difference is this stuff won't break! I've made quite a few projects with this stuff. Anything from small R/C car parts up to small go-karts for my son. This will make a great replacement for any window of same dimensions.
There are a few flaws. It has 8-1/4 sized holes an inch and a quarter away from the edge. You can see the arrows pointing to them in the picture. Also, the paper has been pulled away from one of the corners. This does not in anyway effect the durability of this sheet. The paper is there strictly for handling purposes. This sheet is clear as glass once the paper is pulled away. There is 12"x30" of useable non-marred surface area.
The shipping is set at $20 to anywhere in the continous states. Shipping anywhere else will be addidtional. This stuff is heavy and is expensive to ship. Take this into consideration when placing bid.

Good Luck!
