ABSTRACT:
A pet door assembly having a frame and a security cover. The security cover has a main body with vertical edges and vertical flanges formed near each vertical edge. The frame includes vertically extending channel members for slidably receiving the vertical flanges of the security cover. Each channel member includes an integrally formed wall portion, a portion of which is located inwardly of the flange when the cover is disposed within the channel. The channel members and the vertical flanges engage in an interlocking fit to prevent the cover from horizontally extruding out of the channel, such as by a force applied substantially normal to the security cover, thus preventing the security cover from dislodging from the frame.
