Hold the bottom of the door closer to your feet and the top of the door closer to the exterior wall. Insert the rollers on top of the screen door into the screen door track at the top of the door frame. Slowly walk the bottom of the screen door towards the door opening as you push it up into the track. Lift the bottom of the screen door into the track. Tighten the adjustment screws at the top of the screen door as you roll it back and forth to make sure the rollers stay in the track and the door moves smoothly.
