A screen door can seem complicated since they often slide back and forth on a track with very little effort on behalf of the operator. It is actually a very simple invention that involves a track, a frame, and some wheels in the base. These wheels can be adjusted to allow the door to move more fluidly across the track and allow it to move more freely as it is opened and closed. Some screen doors have simple locks to help you lock the door, which is more for peace of mind than anything else, as anyone or anything can get through a screen door quite easily if they wanted to. If you've grown tired of your screen door, these steps will help you remove it.
