Screens fit all types of standard or oversized doors including in-swing, out-swing, sliding patio doors and multi-panel doors.  For double French doors, two screens are mounted to each side of the door frame and pulled to the center when needed.  Multiple units can be used to screen larger openings.  Phantom door screens feature a roll control option to regulate the retraction speed of the unit.  There is enough “give” in the mesh to help prevent the screen from being damaged if your pet bumps into them, but Phantom is not a pet retention system.
