Morikey Large Dog Door Replacement Flap Review

Intro

I'm The Pet Dude, and I've been swapping out dog and cat door flaps long enough to spot the small details that make a replacement worth buying—or not. The Morikey Large Dog Door Replacement Flap (model PET05) is a budget-oriented swap for people who own the PetSafe Freedom doggie door PAC11-11039. The listing and internal research notes promise a weather-resistant vinyl flap in a plastic frame that aims to match the original fit and function. In this review I walk through the specs the listing provides, what the product actually does in day-to-day use, the installation hiccups owners flagged, and who should consider this flap (and who should skip it).

What it is / first look

At face value the Morikey PET05 is a straight replacement flap: a single (pack of 1) vinyl flap sized and shaped to sit in the same location as the PetSafe Freedom door flap. The listing gives clear specification points I rely on:

• The flap measures 10 1/8" x 16 7/8" (the listing also contains a separate line referencing a 13 x 17-inch flap opening—see the note below on measuring).
• Material types listed are metal, plastic, and vinyl; the frame material is plastic.
• It is marketed compatible specifically with the PetSafe Freedom Doggie Door model PAC11-11039.
• Maximum compatible thickness for the installation is listed as 0.3 inches.
• The replacement comes with screws included and is available in a large size; the listing also shows a pack-of-3 option for the same large model.
• Color shown in the listing is black.

Beyond raw specs, the listing copy promotes weather resistance and says the flap helps keep things "warm in winter and cool in summer," and that Morikey designed the flap to be "tough and wear-resistant" to withstand frequent pet passages and harsh weather. Internal research notes I reviewed reinforce that many owners find the flap fits well and holds up—more on that below.

First impressions out of the box

• Packaging and parts: The kit ships as a single replacement flap (or a multi-pack if you choose the three-pack option) and includes screws to attach it to the existing door frame.
• Color and finish: The listing specifies black. The photographed unit shows a dark flap in a plastic frame consistent with a replacement part intended to mirror the original PetSafe look.
• Notable listing language: The listing repeatedly emphasizes easy installation—"simply use a screwdriver"—and direct fit for the PAC11-11039, which is a strong selling point if your existing frame is the same model.

In daily use

Owners who chose this flap mainly wanted a cost-effective, drop-in replacement that behaves like the original. The product is positioned to be a no-fuss swap so your pets can keep coming and going. Here’s how it plays out across typical day-to-day scenarios.

High-traffic doorways (multi-dog homes)

The listing and research notes emphasize the flap's wear resistance. Internal research notes include several first-hand themes saying the piece is "sturdy" and "well made," and that it tolerates heavy traffic better than more fragile aftermarket flaps. If you have multiple dogs running through a side door, that robustness is the main reason to pick a replacement instead of a cheap thin vinyl piece that tears quickly.

Solo dog or cat households

In single-pet homes the flap behaves like a standard flexible vinyl barrier: it returns into place when pushed and is meant to block drafts and rain. The listing claims it helps keep the space warmer in winter and cooler in summer. That aligns with its intended purpose as a direct replacement for a flap that has simply aged or cracked.

Installation and fit in real life

One of the selling points is "easy installation," and the listing explicitly says you only need a screwdriver and the original pet door structure. Internal research notes back up that it's generally an easy swap: multiple notes report the flap fits perfectly or very closely and that installation took only a few minutes.

That said, there are a few caveats to be aware of:

• Hole count and alignment: The listing states the flap has five holes at the top and comes with screws. Internal notes mention some owners observed differences (some older flaps may have six holes), so double-check the pattern on your existing frame before ordering.
• Screw length: Multiple notes say the included screws are a bit longer than original hardware. Most owners found them effective, but at least one strong critical theme said the screws were the wrong size for their frame—so expect to verify fit and have an alternate screw set on hand if needed.
• Trimming: A few notes say the flap was "a tad bit off" and required a small trim to fit perfectly. The listing warns buyers to verify dimensions before buying, and I agree—measure the flap dimensions on your door and be prepared for light trimming if your frame tolerances are tight.

Materials & build quality

The listing lists materials as metal, plastic, and vinyl, with a plastic frame. Those are typical choices for aftermarket replacement flaps: vinyl for the flexible flap itself, plastic for the frame, and metal present likely in the screw hardware or internal fasteners. The product blurbs call out "high quality material" and use terms like "tough and wear-resistant." Internal research notes support that impression: several owners described the flap as "sturdy," "well made," and "just as good as the original."

What I take away from that combination is this: Morikey aimed to reproduce the original PetSafe parts in feel and function. The plastic frame keeps weight down and is consistent with factory replacements, while a heavier-duty vinyl flap will better resist scraping and repeated impacts from active pets.

Finish and small details

• Frame: Plastic frame should be treated like the original—functional but vulnerable to cracking if overtightened or if your door frame is very brittle.
• Flap: The vinyl flap appears to be thicker than bargain-bin alternatives based on the listed "wear-resistant" language and owner notes praising durability.
• Hardware: Screws are included. Internal notes repeatedly mention they work for many owners but are sometimes longer than originals, which is worth watching during install.

Safety considerations

Pet safety is my top priority, and even replacement parts can introduce hazards if they don't match your frame exactly. Here are the safety points the listing and internal notes let me document.

Choking and ingestion

The product is a door flap and not a chew toy. The listing and internal notes do not report any small pieces detaching during normal use. Still, if your dog is an aggressive chewer who gnaws on door flaps, no replacement vinyl part is reliably chew-proof—monitor heavy chewers and replace damaged flaps promptly.

Screw and installation hazards

Two installation-related issues appear in the internal notes and are worth calling out:

• Screw length: A recurring theme is that the included screws are longer than the originals. Most owners found them effective, but at least one account explicitly called the screws "not the correct size." Too-long screws can protrude past a thin frame or screw into internal doorwork—measure and file or swap screws if necessary to avoid sharp ends that could scratch or cut pets passing through.
• Trimming and cutting edges: If you need to trim the vinyl to make it fit, take care to cut smoothly and de-burr the edges so there are no sharp bits that could nick a paw or snag fur. The listing doesn't specify trimming guidance; this comes from installation notes where owners trimmed a "tad bit" to fit.

Fit and escape risk

The listing specifies a maximum compatible thickness of 0.3 inches. If your door or panel is thicker than that, the frame won't seat properly and gaps could allow drafts or even an opportunity for a small pet to wiggle at the edge. Always measure your door panel thickness and the flap opening before buying.

Weather sealing

The listing says the flap "provides a seamless barrier for harsh weather conditions and outdoor elements" and claims it helps regulate indoor temperature. If the flap fits the original frame and the magnets return it properly, it should reduce drafts the way the factory part did—again, fit is central to making the weather-sealing claims matter in practice.

Who this is for / who should skip

I try to be practical here: replacements are about matching fit and value, not about swapping to a different style of door. Use these notes to see if this is the right replacement for your setup.

Who should consider the Morikey PET05

• Owners who have a PetSafe Freedom Doggie Door PAC11-11039 and need a direct replacement flap sized to match the original, since the listing targets that model specifically.
• Large-breed households: The product is listed as "Large" and the listing's dog breed size is "Large," so it is intended for larger openings and pets that use those openings.
• People who want a budget-friendly aftermarket replacement rather than ordering a pricier factory part—internal notes highlight that many buyers appreciated the lower cost.
• Shoppers comfortable with light DIY work: installation should be a straightforward screwdriver job, and a few owners trimmed a small amount of material to get a perfect fit.

Who should skip or be cautious

• If your door or frame is thicker than 0.3 inches, the listing says this flap has a maximum compatible thickness of 0.3 inches—so it likely won't seat correctly.
• If you require a guaranteed exact match to factory hardware (screw lengths and hole patterns), be cautious. Internal notes include at least one critical report of mismatched screw size and one note about hole-count differences (five holes vs. six holes on some originals).
• Aggressive chewers: the listing presents a durable flap, but no vinyl flap is chew-proof. If your pet chews on door flaps, consider monitoring or selecting a different access solution designed for heavy chewers.

Verdict

Overall, the Morikey Large Dog Door Replacement Flap (PET05) is a pragmatic, budget-oriented replacement for the PetSafe Freedom PAC11-11039 model. The listing provides clear dimensions (10 1/8" x 16 7/8"), material callouts (metal, plastic, vinyl; plastic frame), and a maximum compatible thickness (0.3 inches). Internal research notes reinforce the listing's claims about fit and durability: many owners report a snug fit and report the flap holding up well to frequent passages. The trade-offs are mostly about installation details—screw length and occasional need for a small trim—and one strong negative report that the flap was "too long" and screws did not fit a specific door frame.

If you match the listed compatibility, measure carefully, and keep a spare set of screws handy just in case, this is a value-focused alternative to a pricier OEM replacement.

Check before you buy (quick checklist)

• Measure your current flap opening and compare to the listed 10 1/8" x 16 7/8" dimensions (the listing also mentions 13 x 17 inches elsewhere—measure your frame to be safe).
• Confirm your existing pet door is a PetSafe Freedom PAC11-11039 or has the same hole pattern and mounting points.
• Check your door/panel thickness—do not exceed the maximum compatible thickness of 0.3 inches listed.
• Note the listing shows five top holes; if your original has six, verify alignment before installation.
• Keep a short screwdriver and a spare set of screws on hand in case the included screws are longer than your frame tolerances.
• If trimming is required, cut and deburr carefully to avoid sharp edges.

Final thought: For the price-conscious pet owner who needs a functional, long-lasting flap and who is willing to double-check fitment, the Morikey PET05 often gets the job done without a fuss. Just respect the measurements and hardware notes and you should be fine.
