0.05” Aluminum hurricane panels in various sizes. (The 74.5” panels may be a galvanized metal but they are not heavy). Two 74.5” panels fit my 62” H x 16” W window. With overlapping the panels. There are four panels so it will cover two windows of this size. The panels will also cover a window up to 44” wide with 4” extending on each side of window. Panels can be over lapped more to accommodate smaller width windows. I also have two 36” panels that cover a small fixed window almost like a port hole. All screws and wings nuts included. Panels were bought prior to Hurricane Wilma and have been used maybe three or four times. If you would like more information please contact me. Reasonable offers will be considered. *Please note that we are selling at 50% off of retail prices and no sales tax* Dade county approved. Paperwork included.
