    Abstract: A magnetic customized garage door screen includes a screen surrounded by a border.

The magnetic strips can be secured to the border using adhesives and the metal strips can be secured to the door frame using double-sided tape. The door screen can also include a zipper or handles along a side thereof to allow entry into or exit from the garage. At least the border and metal strips are color matched to the color of the door frame so that the metal strips are inconspicuous when exposed and the border blends in with the door frame color when installed.
