First of all. Great Screens, Good Product. Word of Warning. Measurements are very tricky. Old screens and window sizes vary with the same side of the window, causing inaccurate measurements. I measured in several different spots on my old screens / width of windows opening. ...and my screens came 1/16th too large. They almost did not fit. But the good news is. With a little effort, they all slipped in to place, with an added bonus that now they fit very snug, thus no bugs get in. But I need to be very careful taking them out.
