I ordered and received new screens for five of my downstairs windows. I was a little nervous because I took all the measurements myself and if I were off even by 1/16" then I would have had $400.00 in unusable screens that I couldnt return. Thankfully they all fit like a glove, and we upgraded the screen material to their "pet resistant" version so hopefully Ill get a couple of years out of them before the cats claw them to ribbons.
