My cat has torn a nice hole in the screen at the bottom so i want to replace the screen with the thicker 'pet screen'. I see how to remove the screen material and even how to secure the new material from the frame so that's not a problem.
I tried lifting the whole screen door up and hoped it would allow me to get the rollers at the bottom off their track but that didn't work. There's no room to lift it up. What am i missing?
