A wind chain can protect your door and door hardware (closer, hinges) against damage due to gusts of wind blowing the door open wider than it should. Installation is easy.
Screen door tracks and channels are used as the bottom rail for the screen door to ride on, and for the top track that guides the top of the door. The channels are also used on the door jambs to provide a way top get the screen door to fit snugly against the side jambs with no visible gaps.
