What I do is adjust the bottom rollers first to get the patio screen to roll smoothly. Next, I adjust the top rollers just enough to keep the screen door from jumping off the track. Turn the adjustment screws at the top a little at a time, maybe even to the point were the door is hard to slide then back off the screws. Let me know if that works!
