A fitted cover closes the pet-door opening when independent access is not wanted.
Choose the installation model first, then verify pet size, rough opening, frame dimensions, finish and flap package.
Please pick the appropriate size replacement cover for your pet door. NOTE: Did you purchase your pet door prior to 2005? If so, we will need to make the cover narrower to fit the older metal track we used to use in our…

Choose your size →Choose the cover by the existing pet-door size and frame orientation. Load direction—top, left or right—matters on compatible interior frames.
Covers and locks are part of access management, but they do not replace the home’s primary security system or normal door and window locks.
Match the cover to the existing frame size and load direction, then choose compatible lock hardware for the intended access-control routine.
The safest way to order Dog Door Security Covers is to identify the installed door before choosing the component. Record model, named size, approximate purchase date, frame orientation, number of flaps and any SKU or order documentation. Photograph the part in place and the surrounding hardware. A replacement described by a familiar word—flap, magnet, cover, strike or weather strip—can still vary by size and application. Match the system first, then decide whether one component or a fuller kit is the sensible repair.
Top-, left- and right-loading frames require the corresponding cover orientation. Verify the model and clearances before assuming a replacement will slide into the track.
Use manufacturer dimensions and the original frame identity whenever available. Old flexible parts can stretch, curl or be trimmed, making a casual measurement unreliable. Covers depend on frame size and load direction; magnets and strikes depend on their mating hardware; wall tunnels and buildouts depend on construction depth. If identification remains uncertain, compare multiple dimensions and photos before ordering instead of drilling, cutting or modifying a new part to imitate the worn one.
Dog Doors Depot carries 11 standard flap sizes from Small Medium through Giant, including tall intermediate sizes that separate height from width. Use the individual animal rather than the label as the decision-maker. After the clear opening is selected, compare the exact product variant because model families can use different frame, tunnel and cutout relationships. If every standard choice creates a meaningful compromise, use the custom-size workflow and keep the submitted dimensional basis attached to the order.
Keep cover tracks clean and check knobs, pins, strikes or plunger hardware for smooth engagement after installation.
Read the component instructions and document the original orientation before disassembly. Work on a clean surface, organize fasteners and distinguish existing screw holes from rivets or manufacturing marks. After installation, cycle the flap or cover repeatedly and confirm magnets, strikes, tracks and locks meet correctly. A replacement should move freely without being forced. If it binds, inspect alignment and compatibility rather than immediately enlarging holes or removing material.
A fitted cover closes pet access and helps close the opening when it is not in use. It remains supplemental to the building’s primary doors, windows, alarms and locks.
A repair visit is an opportunity to inspect the connected system. A new flap may still leak if weather strip is missing or the frame is out of square. A cover may not lock if a track is damaged. A magnet cannot close a badly curled panel. Clean the frame, correct debris and note the date and part number used. Keeping that small service record turns the next repair into a direct reorder instead of another identification project.
Do not describe a pet-door cover as the home’s complete security system and do not force an incorrect cover into a mismatched track.
A strong preflight is deliberately repetitive: measure again, check the dimensional label, compare both faces of the opening and read the exact manual. Confirm that the host door, wall, screen, glass or kennel panel remains safe and functional after the cutout. Record uncertainty instead of converting it into a guess. If structure, utilities, ratings, glass type or water management are unclear, pause the product decision and have the appropriate installer or trade verify the condition. That short review is less expensive than correcting an incompatible made-to-order frame.
Move from shortlist to order only after four checks agree. The pet fits the clear opening; the building can accept the rough opening and full frame; the selected model matches the surface and thickness; and the flap, finish, cover and accessory choices match the intended use. Save the product page and model instructions with a labeled measurement sheet. For multiple openings, give each location its own ID and configuration. Review every line before submitting because made-to-order dimensions and options should not be inferred from another opening or corrected after fabrication begins.
Read the finished configuration back as a complete sentence before approving it: model family, named size or custom dimensions, measurement basis, frame finish, flap count, installation surface, finished thickness and mounting location. Then compare that sentence with the cart, worksheet and installer scope. This catches a correct measurement attached to the wrong model or a correct product attached to the wrong opening. When two pets share the door, confirm the widest body, tallest shoulder and lowest comfortable step-over still work together. Photograph the taped frame outline and keep that image with the order so the installer can verify placement before cutting.
Attach the new part number, order date and installation photo to the original model and size record. Note whether connected items—magnets, strikes, weather strip, tracks or fasteners—were replaced or simply cleaned and adjusted. This prevents the next person from measuring the replacement as though it were the original specification. It also reveals repeat-wear patterns that may point to alignment, pet traffic or exposure rather than a defect in each successive service component.
Before submitting a made-to-order request, make sure the saved measurements tell one clear story: which pet was measured, what each dimension represents, where the door will be installed, and which options were selected. If the project requires a contractor or glass professional, keep that person’s verified construction dimensions beside the pet measurements so neither set is mistaken for the other. A complete record makes the order easier to confirm now and makes future flap, cover, lock or weather-strip service much easier.
Keep the measurement sheet, exact product page and installation manual together through ordering and installation.

Measure from the floor to the top of your pet’s shoulders and measure the widest point of the body. The flap should generally sit about 1–2 inches above the shoulders, with a comfortable step-over height. Use the actual pet measurements rather than breed averages.
Yes. Frame color, flap count, size and installation type are selected for your opening. Review the measurements and selected configuration carefully before submitting an order.
Yes. Replacement flaps, flap kits, magnets, weather stripping, locks and covers are available. Match the replacement part to the original pet-door size and model.
