Pride MD400A Flap Assembly – For MD400 Pride Pet Door

Pride replacement flaps are available in four sizes to fit all pride pet doors and pet door panels for sliding glass doors. Flaps are black rubber only. According to the manufacturer, Pride flaps are interchangeable with Johnson Pet Dor flaps. They also are the only flap currently available to fit the discontinued Geisler pet door which was a knock-off of the Pride pet door. Pride Flap Identifying Information Pride flaps consist of two parts : A rectangular central flap and a ‘U’ shaped piece that overlaps the flap and the frame on one side. When the pet pushes in one direction both parts swing away. In the other direction, only the central section swings. Pride locking covers are fiberboard with one side painted bright white. This very visible color alerts the pet that the door is locked. It may be mounted on either side of the pet door. Pride pet doors have these manufacturer numbers on a label on the frame. Flap dimensions shows are inside the ‘U’ shaped gasket. Hot Tip : We’re measuring inside the ‘U’ shape. So long as the label matches the manufacturer part number, don’t worry if your measurement is slightly different.
