MIAOTONG Large Dog Door Replacement Flap, PVC, Weather-Resistant with Magnetic Closure

The flexible PVC flap is designed to replace a worn panel while letting a dog or cat pass through an existing pet door. It measures 10 1/8 by 16 7/8 inches and has five screw holes along the top, details that matter when matching it to the opening and mounting points already in place.

A magnetic strip at the bottom is intended to help the flap close against the frame. The package includes the flap and five screws, the door itself is not included.

Key takeaways

This is a replacement part, not a complete pet door. MIAOTONG lists it as compatible with the PetSafe PAC11-11039 large flap and several PetSafe door types, including wall-entry, sliding-glass, patio-panel, aluminum, and plastic doors. Compatibility is the main buying question: compare your current flap’s dimensions and top screw-hole layout before ordering, rather than relying on the word large alone.

The PVC is described as flexible, durable, and weather-resistant. The magnetic bottom closure is intended to help the flap sit back in place after a pet passes through, while the material is meant to let pets move in and out without assistance. It’s a great fit if the existing frame is in usable condition and you need to replace just the flap instead of the whole door assembly.

Who it’s for

This replacement is aimed at owners with a compatible large pet door whose flap needs changing. It may suit a household where a dog or cat uses the door regularly and the existing mounting points match the five-hole layout. For a practical example, if a pet uses a patio-panel door to move between the house and yard, replacing the flap can retain that setup without replacing the entire door.

Buyer feedback is generally favorable about fit, function, and installation, but those reports are not uniform. Some buyers say it fits their PetSafe door and works like the original, others describe sizing differences. Feedback on the magnetic seal and included screw dimensions is also mixed, so compare the new part with the old flap and its mounting holes before starting. Not the best choice if your door uses a different size or screw pattern, or if you need a complete door rather than a replacement panel.

Tips for day-to-day use

Before installation, check that the old flap’s dimensions and top holes correspond to this large replacement. The product information says installation requires a screwdriver: remove the existing flap, position the replacement, and secure it with the included screws. Take care not to assume the screws will suit every existing hole, some buyer feedback reports a mismatch in screw size.

After fitting, observe whether the bottom magnet meets the frame and the flap returns to its closed position. The magnetic strip is intended to help limit exposure to outside conditions and insects, though buyers report differing results with the seal. The flap is described as weather-resistant, but the listing does not provide a rating for the assembled door or a guarantee of a particular level of sealing.

Final verdict

The MIAOTONG flap is a focused alternative to replacing an entire pet door when the existing door is compatible and its frame remains serviceable. Its specified dimensions, five-hole top, flexible PVC construction, and magnetic closure give buyers useful points to match against the old part. If the size and mounting layout align, it offers a straightforward replacement approach, if they do not, choosing a flap made for the exact opening is the safer route.
