The way to get the best results when installing a patio screen door is to first make sure you measure right, don’t get a sliding screen door that is too big or too small. Next on the list is to vacuum and clean the track, make sure there is no dirt gravel or rocks on there because you will have problems with the screen rollers sliding properly. Make sure each individual roller is lubed as-well.
After you cleaned the track, lubricate both top and bottom. Now you are ready to install the screen. The tools needed are a phillips screw driver and a flat head screw driver. Grab the screen and put it in on top first then push the bottom in making sure the rollers are centered on the track. All screen doors have four adjustment screw holes to get the door straight, make sure you use them to balance the door.
