Review on Heavy Duty Magnetic Screen Door for Doorway and Sliding Door - Fits 38x82 Door Size with Fiberglass Mesh and Strong Magnets - Screen Dimensions: 40x83 Inches by Matthew Frandsen

Read all the ratings and ordered the size larger that my door -- perfect -- door size would not have worked!I first mounted the screen only from the top, equally from the center of the jam . my wife went left and I went right. It hung perfectly and we could see just where the side Velcro should be mounted for a snug fit up and down the side jams and marked both jams. I held the screen away from a jam while wife applied the Velcro to door jam where we had marked it and then we set the screen on the Velcro. Then I held the other side of scree away from that jam and wife applied Velcro to that jam where we had marked it. Then we stuck screen on Velcro.It fit perfectly with no snags. bulges or opening in magnet area.Most people had problems caused by applying the Velcro on the sid jams and top all at the same time. Follow our process and all should be perfect.After a week of regular usage, I needed to use the tacks along the top because it pulled away.
