  • Best pet door flap I have purchased! review by Lauren
    5 5 Best pet door flap I have purchased!

    I've had a pet door for 20 years and the endura flap is by far the best one! It doesn't warp in the Texas sun (but it's also not in full sun all day) and it seals tight. I own a pet care business and I have dogs going in and out all day. It's a great flap!

  • Excellent product. review by Diana
    5 5 Excellent product.

    Our dog door is like new again! One of our two dogs has taken to slamming through the door and nipping at it on her way. It is good to know we can replace the flap and be good to go. Also training her not to mangle the new one. Wonderful help from customer service identifying the style and sized needed.

  • Replacement door for panel review by Roseann
    5 5 Replacement door for panel

    Thank goodness I kept the original papers for my pet door panel from more than 10 years ago. It was very simple to find the replacement door online. It was a perfect fit and only took about 15 minutes to replace.

  • Excellent door for the price review by Diane
    5 5 Excellent door for the price

    Almost as nice as our endura door but a lot less expensive

    Editor's Note: This is the same flap that comes with all Endura Flap doors, only it comes as just the flap itself.

  • good product review by Earl
    5 3 good product

    While it is still the best door on the market, it could be better. the metal trim on the bottom of the door will eventually fall off. When that happens the magnets will fall out and most likely will be lost. I was finally forced to wire the metal trim on. Also the rivets that hold the two halves of the flap together will fail. I had to use bolts to hold the halves together. Also the side magnets will also break and come out.
    I think that it could be designed to be a little more rugged. Without much more expense.

    5 5 Fits my endura flap!

    Fits my endura flap pet door perfectly! Since you have to basically uninstall the frame to replace the flap, it comes with a lot of extra goodies. The replacement process was not easy and took a while to complete.

    5 4 very nice it comes with so much stuff

    We only needed the flap but it comes with more magnets and parts so now those serve as spares!

    really quick turn around after ordering, these things hold up after years except when they get chewed :(

  • Durable yet flexible review by Jerry
    5 5 Durable yet flexible

    The perfect medium between a rigid and flexible flap. We tried the hard rigid flaps for a while since my dog kept chewing up the flexible vinyl ones, but he really didn't like it. He can't seem to get through this one, which is great. Had to repurchase due to some normal wear & tear since we've had the door for many many years.

    I received the replacement door in a very timely manner but haven't installed it yet.. I have had my pet door for 4-5 years or so and my dog loves going in and out of. It is starting to show a little wear but I am waiting until winter is on it's way so I can install the new flap and be ready for another cold, snowy winter in Reno NV.

  • frustrating install but worth it review by cassie
    5 4 frustrating install but worth it

    I have a patio door panel purchased 5 years ago. With 8 dogs using it, I conservatively figured the flap had been used at least half a million times. The two layers of the flap finally separated allowing dirt in between that I could not clean. The bottom metal piece also came loose. Time to replace the flap.

    Directions were easy to follow. My difficulty was removing the panel by myself and sliding out the old flap. Two of the screws I was to loosen had frozen and I could not turn them. The tracks on either side had also frozen. Probably 5 years worth of dirt?

    WD40 to the rescue and I was finally able to manhandle the panel out and the replacement panel in. The flap fit perfectly.

    So, nothing wrong with the product. Just hard to manipulate the panel by myself. But, after half a million uses and abuses, I am very impressed with the product. It is more costly than other brands, but absolutely worth it!

  • Design Suggestion review by PreventChewing
    5 2 Design Suggestion

    (ed. note: We are currently working on a redesign for the threshold. The new ones will be plastic making them a little quieter and the full width of the flap.)

    We have had to order and install multiple doors because of chewing. I think this could be prevented by extending the metal across the bottom to prevent a starting point for the chewing which seems to be the corners. As suggested we did apply a gel with pepper to help prevent but this also prevent the seal from working in cold weather.

  • Great part but directions missing crucual step review by nspitzer
    5 3 Great part but directions missing crucual step

    Three things to keep in mind if you need to replace a flap that will save you a lot of hassle, two trips to Home Depot and a leaky flap:

    1: Before ordering, visually check that the flap hanger rods are not bent. It might not be obvious without close inspection. They are cheap (less then $5 each) so it may better to order them just to be safe. I ended up getting stainless steel rod the correct size at Home Depot and cutting it to size.

    2: Be aware you might need to also need to replace the weather stripping. A second trip to Home depot with door in tow found the right size

    3: MOST IMPORTANTLY: The directions miss an absolutely crucial step: When installing you MUST make sure that the magnets in the flap and sash bottom align correctly. If you install the replacement flap backwards the magnets in the bottom of the flap and the sash will repel instead of attracting and you will get a gap. If this happens simply turn the flap around and you should see everything work much better. Found this out after much head scratching about why both flaps in my double-flap installation left 1/4 inch gaps and bottom flap would not seal.

  • LOVE IT review by dk
    5 5 LOVE IT

    I've had my pet door insert for patio doors for about 12 years. This door has had an extreme amount of use and still looks like new. This pet door accommodates 14 dogs (Chihuahua size to German Shephard), so it's pretty much in use the entire day and most of the night, I finally had to replace the Endura Flap because it was chewed on by a puppy and lost the ability to seal tightly. The only regret I have is that I put off ordering a new flap for almost a year, dreading the hassle I thought I was going to have installing the new flap. WRONG! It was very easy to install - fits perfectly. Fast shipping! LOVE this pet door! Don'[t know what I'd do without it !!!

  • Good but sometimes sticks review by Lisa
    5 3 Good but sometimes sticks

    This is a nice heavy door but this replacement one is not closing all the time tightly. Very often I look at it and it has not sealed up evenly so there is definitely some airflow going through it. I wish it sealed up evenly like the original one I received with the door.

  • Great door review by Sue
    5 4 Great door

    This is a great door and very well insulated. We live in Wisconsin where it is cold and can be windy. The dogs had no problem learning the double door system. We did have a problem with my Australian shepherd pup chewing on the door so a friend gave me some freshly dried hot peppers, which I coated on the edges of the door with Vaseline (in winter) and problem solved. The only problem with the actual door is that it is a bit frustrating trying to get the screws in for installation. I would rate the door a 5 and the installation a 3. Overall, it is a great door!

  • Excellent Door review by BigDog
    5 5 Excellent Door

    I have had this dog door for 8 years and three German Shepherds and one Alaskan Malamute. The door and its hardware show no age and very little wear. I am very satisfied. Unfortunately, a visiting dog was kept locked outside during dinner and he chewed the door apart. Mistake on our part, he's a known destructive chewer. I replaced the door recently. It seemed rather expensive for all it was but is easily worth it. I know I'll get a few decades use out of it. I've heard questions about wind and leaks. My door faces north in the midwest. It stays shut until the wind gusts over 30mph, then it blows open. When it's closed, it doesn't leak noticeably, and I looked hard for leaks. Excellent product.

    would give the door 5 stars if it had spring clips to hold it in place, cleaning door is a pain. If I could remove, clean it and replace it, I would say that would be great.

  • Great Doggy Door review by Bunjy's Dad
    5 5 Great Doggy Door

    Love this door. We had a rigid flap type door first, and our dogs destroyed it....We had to replace the flap 3 times. it was easy to do but was getting expensive...Then we found this door. It's awesome. Someone in the reviews here said they can't block the dogs out from the house from the inside only the outside??? Dude your dog door is in backwards, because when we slide the solid partisan in the track FROM THE INSIDE it works great. Nothing is gonna come through this door. Now replacing the flap on this door is a pain. As stated in another review here, you do need to take the entire dog door apart to replace it. Not a huge deal, just a bit time consuming....Overall a wonderful door. We have 6 large dogs all over 70 lbs and we have the XL door. It's great....

  • good quality review by SMC
    5 4 good quality

    Good quality and lasts for quite some time. I have the sash window version. My only complaint is that you have to take the entire unit out of the window and take it apart to replace the flap. Seems there ought to be an easier way to do this!!! Since my windows are slightly off in size, it was hard to install the first time around and certainly no easier the second time around.

  • Bought flap as a replacement review by RobG
    5 5 Bought flap as a replacement

    I bought this flap as a replacement after the dogs chewed up the original. I found you can't block the door on the inside to keep the dogs out. Best to block the door on the outside.

    Overall a great product. Well made and seals against drafts amazingly well. The flap was easy to replace as well.

  • Worth the effort - Excellent door review by Texas Shirley
    5 5 Worth the effort - Excellent door

    I have the patio door model. It is simple to remove the unit and replace the flap. I installed it the same way I originally installed the flap. It was a me, myself and I job. If an old lady (70) can do it anyone can! This is the best doggy door I have ever had and I have tried several. I have large dogs. Rhodesian Ridgebacks weighing between 90 and 135 pounds. The original flap in the HOT Texas weather lasted 2 years. Dogs never had a problem with it and my cats can get in and out also.

  • Easy install and well made review by Doggymom
    5 5 Easy install and well made

    Original flap lasted 2 years with 3 large dogs. Probably would have lasted longer but my last rescue was spooked by the magnets clicking tight, so I removed them for the summer while he got used to running in and out with the other dog. In the fall I ordered the replacement for winter weather. Yes, you do have to take the insert out of the door to replace the flap, but the quality and fit of the pieces is well worth it. After a few times he was running in and out just like he did without the magnets. Wonderful product for sliding glass doors!!!

  • Terrible for Sash Window review by Brian
    5 1 Terrible for Sash Window

    The directions that come with the replacement flap are only for the "Quick Panel" version. If you have the quick panel version, definitely buy this replacement flap.
    But, if you have the sash window, think twice - the instructions are horrible.

  • Excellent durability, hard to replace review by Debbie
    5 3 Excellent durability, hard to replace

    The door and flap are very sturdy, and the first one lasted three years, with two big dogs running in and out all the time. Very, very weatherproof, too.

    My problem came when I had to replace a chewed up flap. It took two people over an hour, because you have to remove the entire door and take apart the whole section in order to install the replacement flap.

  • Wonderful product review by Mel
    5 5 Wonderful product

    We bought a Pet Door several years ago & loved it so much we bought a second one for the downstairs door as well. My puppy has chewed a couple of the flaps off (which we expected), however, replacement was pretty simple & would never be without one again. My sister-in-law has a cheaper pet door and our Patio Pacific is so much better quality. The flap seals much better, however, I would love to see a metal flapper as an option in the future. Definitely recommend.

    ed. note. - We considered metal. Problem is safety. When a pet exits partway, is spooked and pulls back suddenly, you want the flap to give. There are injuries every year in exactly this circumstance.

  • Amazing review by Duke
    5 5 Amazing

    Bought the door for my 5 Jack Russel's around 2006. Recently my husband locked them outside and they chewed up the flap door. Imagine my delight when instead of buying the whole door I only had to replace the flap. Simple to re install and the dogs are back in business. Quality is incredible. If you could only see them running out that door one after the other - you would wonder how the flap lasted this long in the first place. A definite case of you get what you pay for. Money well spent on this terrific product. Would buy it all again and recommend to anyone looking.

How to Replace the Flap in a Door


How to Replace the Flap in a Panel


Replacing the Flap in the Sash Pet Door

Q: Does the Endura flap replacement come with the rod?

A: The rod must be purchased separately, as 99.9% of the time the rod will be re-usable even if your pet tears up the flap. Endura Flap Replacement rods can be purchased on our website.


Q: Why is the double flap Endura door 1" shorter than the single flap version?

A: The single flap and double flap patio pacific replacement flap will be identical, although the space available for the pet to go through changes due to the thickness of the flap. The only reason we say the double flap is shorter is because you have 2 flaps that will hit each other as the pet is going in or out. Since the flap is about ⅞” thick when the first hits the second you lose that amount of space in the top. This image may give you a better understanding of the situation we are explaining.


Q: Can I use this replacement endura flap on pet doors from a different manufacturer?

A: No, this flap is only compatible with Endura Flap Pet Doors.


Q: What does the flap come with?

A: It comes with hole plugs, pivot washers, and magnets for the bottom of the flap.


Q: How do I replace the flap?

A: You can visit the 'Videos' tab for detailed instructions on how to replace the flap.


Q: Do I need to remove the frame to take out the flap?

A: Yes. There is a video on how to replace the flap in the 'Videos' tab.


Q: How do I know what size I need?

A: You can measure your flap dimensions and compare them to the 'Flap Size' in the size chart.


Q: Will this fit into an Patio Pacific Endura Flap pet door I have purchased over 20 years ago?

A: Nope, we just started making the Endura Flap in 2004, so if you have an older door it is possible you have a PetSafe Classic flap.


Q: How many magnets come with the flaps?

A: The small and medium come with one magnet and the large and extra large have 2.  Note the extra large replacement flap did used to have 3 magnets.


Q: Can I purchase the magnets separately?

A: Yes, they are available here.


Q: Can I purchase the retainer clip separately?

A: Yes, you can purchase them at this link.


Q: Can I purchase the hole plugs separately?

A: Yes, they are available at this here.


Q: Can I purchase the side magnets separately?

A: Yes, they are sold at this link.


Q: What's the difference between the patio pacific replacement flap and the Endura Flap replacement flap?

A: IPatio Pacific is the corporate name of the company that manufactures the Endura Flap line of pet doors. If you flap has America's Finest Pet Doors Patio Pacific or Endura Flap on it, they are the same flap.


Q: Are the instructions the same for replacing Endura Flap flaps on each model?

A: No. Your replacement flap will come with specific instructions and we recommend that you watch the corresponding video found on the Video Tab of this page.


Q: My Thermo Panel does not have the hole plugs and brass retainer rings - where do these Endura Flap parts go?

A: The replacement flap packets are designed to be universal for all Endura Flap models. You do not need those parts for your panel so be creative and incorporate them into an art project or discard them, your choice.


Q: Where can I find an Endurace Flap Replacement?

A: To our knowledge, there is no Endurance Flap Replacement. It is a strong possibility that you may be looking for the Endura Flap replacement flap. You can see the details here on this link: https://www.petdoors.com/endura-replacement-flaps.html.


Q: Does the replacement endura flap come with instructions on how to change it?

A: Yes, It will come with instructions. We also recommend that you watch the appropriate video found on the Videos tab on this page.


Q: Is the Patio Pacific Endura Replacement Flap the same as the Endura Flap™ Replacement Flaps?
