Had a screen missing screen that needed to be replaced. Process was easy. Just measure the screen dimensions. I just used a screen from an identical sized screen to measure and fit it into the window with the missing screen to test in stead of measuring the bare window. I initially felt the shipping was high even though the shipping was on the lower end compared to the other companies. However, the screen came wrapped up tighter than Fort Know. I think I could have dropped the wooden frame the screen was shipped in and the contents would have been fine. The screen came in a well put together wooden frame held together by several nails. It literally took me 15 minutes to get the screen out of that frame. I do not think a woman or non handy type person will be able to get the screen out of the box without doing damage to the screen and if not themselves. I couldn't imagine my wife or sister opening that box alone even with tools..
