The Endura Flap Vinyl Panel is the most insulating dog door on the market, designed specifically for vinyl-framed sliding glass doors. Unlike other metal frames common among sliding glass door panels, the vinyl frame fits more comfortably in the track and matches the original vinyl of your sliding glass door. This semi-permanent pet door has a spring-loaded design, which means that no tools are necessary for installation. It safely secures the panel in place without making any permanent alterations, which is ideal for rentals and vacation homes! Engineered to withstand -40 degree weather and 50 mph winds, the magnets that line the flap ensure the utmost energy efficiency and keep the flap sealed during rough weather. The vinyl panel also features dual-pane, Low-E glass, which blocks harsh light without compromising the amount of natural lights coming in.



  • Pet flaps range from small–extra large
  • Fits into existing 1 ½” ‒ 1 ¾” thick track of your vinyl door, occupying space in the door opening
  • Vinyl Panel comes in three adjustable track height ranges:
    • 74 ¾” ‒ 77 ¾”
    • 77 ¼” ‒ 80 ¼”
  • Quality of flap ensures that it stays flexible in extreme temperatures
  • Magnets withstand drafts, leaks, and heavy wind
  • Flexible flap swings on a rod at the top to avoid cracking and flexing
  • Includes a secure locking cover
  • 90 day return policy and a 15 year warranty



  • Vinyl frame applies seamlessly into the track for a highly insulating fit
  • Panel can be removed at any time with the semi-permanent, spring-load design
  • Steer clear from cutting holes or making any permanent changes to your door
  • Comes in white to match the interior design of existing sliding glass door
  • Sturdy locking cover allows you to secure the door when necessary
  • Gives dogs the freedom to access the outdoors without needing you to let them out
  • Structurally sound design is built to last

  • Best Door Out There review by Hannah
    5 5 Best Door Out There

    This door was a game changer for me. The aluminum frames didn't fit correctly in my vinyl sliding glass door, but this one does the job effortlessly. I love that the panel is narrow than some of the other panels on the market, because it leaves more room for people to go in and out of the slider without having to squeeze. A lot of people have complimented how well it matches with my slider as well! Installation was easy, and I'm glad we didn't have to do any drilling! My two dogs love using this door, and I'm very impressed with how well it keeps out the cold and doesn't blow open in the wind. This is by far one of the best purchases I've made for both me and my pups.

  • Sturdy, high quality pet door and panel with next to no installation time review by Russ
    5 5 Sturdy, high quality pet door and panel with next to no installation time

    I was impressed by the easy installation of this pet door, as it doesn't require any assembly; it fits right into your sliding glass door! Not to mention, its finish matches my existing sliding glass door very well, so no need to worry about it standing out.

    The actual pet door is made of aluminum so it can take a bit of a beating from my dogs, but the rest of the panel frame is plastic so it's still relatively light overall. Also, the glass is "Low E," which I've just learned helps keep heat out, i.e. great for summertime in the desert.

    The only concern I have is that I can't lock my sliding glass door with the panel installed, but a wooden rod in the rail works well instead.

    Nice sturdy panel! It matches my sliding door in thickness and color, fits in the door frame well, and is very easy to install.

  • Clean seamless look and easy to install review by Dallas
    5 5 Clean seamless look and easy to install

    This panel looks great in my sliding glass door and I love the long window that keeps the cold out. It was very easy to install and didn't require any tools at all. The fit is perfect and seamless which also helps keep out the weather. The pet door works great and my dog goes in and out without a problem. Would definitely recommend.

  • Great thick and sturdy design providing a easy set up for anyone review by Connor
    5 5 Great thick and sturdy design providing a easy set up for anyone

    This door is a great design, with its great vinyl siding and weatherproofing. Keeps the weather out and my dog happy. The easy installation ability is my favorite part. No hardware needed for this door. Can be easily taken out when on vacation and installed in seconds. Overall very happy with the product.

  • Solid insulating door review by Rick
    5 4 Solid insulating door

    This dog door was incredibly easy to install; two knobs and a spring-loaded top and it fit right into my backyard door track. It's been a cold couple weeks and this door seemed to draw in even less heat than the rest of my patio door.

    The flap has a tough aluminum frame. Its magnets dealt with shrinkage from the cold with no problem and the flap itself kept the cold out without breaking a sweat. The air gap between the layers of the thick glass keeps the outside cold from affecting the room.

    Four stars only because the lhe lock on my door doesn't work with the panel. Customer service at PetDoors recommended a charlie bar if security is a concern.

    The white vinyl matches the rest of my framing perfectly - it looks like it was built into the house! I highly recommend for anyone with a vinyl-framed sliding backyard door.

  • The best pet door option for a vinyl sliding door review by Scott
    5 5 The best pet door option for a vinyl sliding door

    I’ve been looking for a high-quality pet door panel to properly fit my vinyl sliding glass door. Until now the metal framed panels have been too thin, and I did not like the flap options on the other vinyl frame panels I found. The Endura Flap pet door used in this panel gets great reviews and now I know why. It is sealed on three sides with magnets and does not blow open when the western winds blow hard against my home. I like the spring loaded piece at the top of the panel which made it easy to install. It will also allow me to take it out when I go out of town. In addition to all these features two layers of low-e glass help keeps out the summer heat. I’m happy with my purchase and will recommend to my friends and family looking for a similar door.

  • Good solution with a few minor production issues review by Ryan
    5 4 Good solution with a few minor production issues

    Well made door. Flap stays sealed through any weather and the entire piece is made of quality materials. Couldn’t give it a 5/5 because of a few small issues:

    -Pretty noticeable gaps between pieces (although they appear to be sealed)
    -The tightening knobs on the door prevent it from sitting straight in my door

    Overall, would definitely recommend.

  • Better than the aluminum slider insert review by Kelsey
    5 5 Better than the aluminum slider insert

    This door is an improvement over my old aluminum one. It looks and fits better, seems more sturdy. The frame doesn’t freeze up either so there won’t be water dripping all over my floor when it gets below 20. My only real complaint is that it has some aesthetic issues like gaps around the trim where the glass is, so the production quality needs improving, but the door works fine.

  • Looks great and installs easy review by Brian
    5 5 Looks great and installs easy

    I love this pet door! It is the best option for anyone who doesn’t want to cut a hole in their door or wall. The installation couldn’t be easier, you just set it in your sliding glass door frame and loosen the thumb screws at the top and it's in. Plus it goes great with the sliding glass door as if the whole assembly came that way. The pet door itself is awesome too. The magnets seal the door instantly and I hardly notice any drafts at all and my dog uses the door all day long. The only downside is the door is not the quietest but overall I think this is a great product!

  • Great solution with an easy install review by Edgar
    5 5 Great solution with an easy install

    This door is extremely easy to install,twist the knobs at the top, place it on the track, twist the knobs to adjust the height and you’re done. An extremely convenient solution and perfect if you don't want to make holes in your walls or your doors. The door itself is very well made and extremely durable and weatherproof and will last a long time. It is also temporary so you can take it with you if you ever move! The price is definitely justified by the quality.

  • Strong door that’s easy to install in a slider review by Kate
    5 5 Strong door that’s easy to install in a slider

    Sturdy door!

    This door is exactly what I was looking for. My dogs love to play and run at high speed, and this door is sturdy enough to survive their fun.

    I’ve never installed a dog door into a panel before, but this door was super easy to put in with the spring loaded top piece that adjusts for height.

    Overall, it looks great, feels strong, and was a good install experience. Great dog door for a slider if you’re looking for something sturdier but low-profile.

  • A stylish, efficient, and very durable door review by Court
    5 5 A stylish, efficient, and very durable door

    I was one of the lucky few to try the new Vinyl Sliding Glass Dog Door which has a high quality vinyl frame. The frame is 1 ½ inches thick of high quality insulating vinyl. I no longer had to search for a door that was thick enough to stay stable in my track. The Extreme insulation against all four seasons is perfect as I live in a four season climate. This flap has held up against my -10 degree winter so far. Its stayed shut in our high winds and it does not let my heat escape the house. The cold air, snow and rain has not been able to sneak in past the Endura flap. The glass is dual pane and LoE which only adds to the insulation value and it matches the glass on my sliding door.

    The door is stylish and matches the quality of my sliding glass door. Easy install. This panel does not require tools and is as simple to put in as a shower rod. The locking cover is very strong and well designed. I like that this door has a 15 year warranty which shows how well this door is built.

    I loved the wide base on the door. All of the other panels are made for a smaller pencil shaped rail,but this one accommodated my larger rail.

    This door and the design are absolutely amazing. As with every thing there is always improvement to be found. The things I would want to change in this door are for it to have the capability to lock to your sliding door. It comes with a clamp lock and I use a wooden rod in my track, but I think for convenience having something to latch on would be preferred.

    Overall thoughts on this door. It is an awesome step forward for dogs, and a giant leap for dog kind. Dogs all over the world are cheering at the strides made in the dog door world. This door is stylish, efficient and extremely durable.

  • Sturdy panel door with an easy install that will make it through cold weather! review by Jeff
    5 5 Sturdy panel door with an easy install that will make it through cold weather!

    Sturdy framing that matches my slider. The UV coating prevents harsh light from coming in, and the panel itself sits well on top of my shorter monorail track. I didn’t want to do the extra steps that would have been necessary to try to make an aluminum insert fit inside my vinyl slider, so this was a quick and easy solution.The flap itself is thick and does a good job of keeping the cold out, which is important to us as it gets pretty chilly here in the winter.
    Overall, very pleased with the product!

This is very similar in that it has the same height ranges, flap sizes, Endura Flap, and dual pane Low-e glass. However this one is specifically made to fit better in the wider vinyl slider tracks.

This will work in doors that have a recessed track at least 1 1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail

We do include a c-clamp lock, but are in the process of a redesign which will make it capable of mating with certain types of existing sliding door locks

It is meant to easily be put in and removed. You just have to loosen the screws at the top, fit it into the track, and then tighten them. Then to remove it you simply loosen them again and pop it out.

The thumb screws are on the inside of the house so you can't loosen them from the outside.

It comes with a closing cover, and you slide that in on the inside of the house. It is a very secure ABS plastic material that is as strong as a 1/16" sheet of steel.

This door has superior insulating capabilities! The flap has magnets that seal all the way around, and will stay closed in wind gusts up to 50mph. The dual pane glass also compliments the insulating value of you new vinyl door. It is our #1 recommendation for extreme climates.

That column is what we recommend be the range of pet height that would be suitable for that particular flap size. So for example if you pet is 20"tall and could fit though a 10" wide opening, then you could go with the large flap.

You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track.

No, but the you can paint the vinyl to match.

It can still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly.

This panel does not have a adjustable step over, but it is pretty low at 4" so most pets should be able to negotiate that just fine. If you aren't sure if your pet can then we recommend simulating the opening with cardboard. You can cut out the flap size you are looking at, making sure that it is 4" from the edge of the cardboard. Then see if they can get through comfortably.

No, not as long as the track height and width meet the panel specs.

At this time it is not offered in the taller height ranges, but we're working on it!

Small would be Chihuahuas, Yorkies, and cats. Medium would be good for Corgis, Jack Russell Terriers, and French Bulldogs. Large would fit most Labs, Goldens, and Pit Bulls. Extra Large would be good for most Rottweilers, German Shepherds on the large side, and English Labs.

It is flexible, but since it is two pieces sandwiched together it is a little stiffer and heavier than the more economical vinyl flaps.

It is a little foggy, but it is see through.

Nope! That is one of the great things about the vinyl framing is you won't have the the condensation on the inside of the house.

Since this is really our door mount version of the Endura Flap installed onto our vinyl panel you would replace it much like you would one installed in a regular interior/exterior door. This means that you would drill out the hole plugs to remove the screws. Then pull off the flap assembly, switch out the flaps, and reinstall the door onto the panel. All of this can be done without removing the panel from the track.

We do hope to offer that option in the future, but right now we are offering only the Endura Flap options.
