Abstract: A one- and two-way pet screen door kit is provided for installation in an existing screen door or window screen to allow pets to pass through in one or both directions. The door is made up of a rectangular metal frame having a pair of magnetic latches located at the base of the door. The door is supported by a pair of symmetrically and horizontally disposed hinge members located near the top sides of the frame and strengthened at its center by a horizontal luminous crossbar. In the lower portion of the pet door, a pair of slide locks is positioned to lock each side to keep the pet either outside or inside. A pair of swivel locks are located on both sides of the door with locking ears on both inside and outside surfaces for one-way traffic. The magnetic latches maintain the pet door in a closed position when the pet is not using the door, and do not present a hindrance for the pet in using the door.
