  • 30 yr Old Plexidor still working! review by Laura Tobin
    5 5 30 yr Old Plexidor still working!

    I purchased my door for my first two Golden Retreivers, Toby and Tara, in 1987. They lived to be 13 1/2 and 15 yrs old and were very healthy, in part because they were never forced to ‘hold it’ for 8 hrs a day or more. For a number of years, the Petdoors USA catalogue had a letter I sent them printed in the back of their catalogue, thanking them for Toby and Tara’s happy, healthy years. They LOVED their doggie door! I have now owned that SAME large Plexidor since 1987 - more than 30 yrs - in 3 homes (re-installed twice) through 7 Goldens, countless rescue fosters, visiting dogs and one cat - I’ve replaced springs once and weatherstripping, but it’s still going strong with daily use by 2-3 pets. For the last few days, one door has been sticking open, so I’m ordering a 3rd set of springs - and Petdoors USA is now online instead of by catalogue- still standing behind their amazing products!
    Definately one of the best and most economical purchases I’ve ever made, especially when you consider the health benefits to your pet!

  • 5 star review by none
    5 5 5 star

    not only are the doors great but the service is wonderful. I needed some new weather stripping and had no idea how to put it on. the lady I spoke with not only was kind and understanding but told me step by step what to do. and said when I received it if was still having trouble just call and she would walk me through. fortunately it was as easy as she said and now the doors are air tight again.
    great company.

  • Seems like the best security features review by Terry
    5 5 Seems like the best security features

    There is a panel to go over and a lock/key set! I feel safer with this installed and it has so many security features. It's so durable feeling and looking, no way this can get destroyed by chewing or big dogs going through it.

  • I would own nothing else! review by Craig
    5 5 I would own nothing else!

    We bought a medium door and installed it about 15 years ago. We've had two small dogs the entire time. Several years ago, our two dogs had worn out the first set of swinging doors. The replacement doors worked but did not have quite the same firm fit. So, we ordered a new door assembly. It plopped right into the old opening and we're up an running again, good as new. I cannot recommend highly enough the Plexidor pet door. It seals perfectly in very cold and very hot weather.

    Our two dogs beat these doors to death, going in and out at least 100 to 200 times a day each. Often one goes in at the same time the other is coming out. When we watch TV at night, the dogs make the door sound like ping pong tournament.

  • Love the doggy door review by Louise
    5 5 Love the doggy door

    I love the doggy door and so have my dogs. It gives them so much freedom and we don't have to rush home to let them out. (We also have an invisible fence). The dogs get plenty of exercise because they are able to go out by themselves and runs around the yard. I think everyone that has a pet should have a doggy (or cat) door. Can't say enough positive things about it.

  • Cats love it review by Joan
    5 5 Cats love it

    My cats love it. I have an enclosed front porch that is their domain, and the door gives them the freedom to come and go as they please. This is actually the second door I have owned. The first one was used almost 30 years, and when we did some remodeling I decided it was time for a new door.

  • Great for Active and Older Pets review by Sadie's Dad
    5 5 Great for Active and Older Pets

    Since dogs always want to be on the other side of the door, my only regret is that I didn't buy this door sooner.

    It's been a lifesaver for our dog, since she can come and go at will.

  • Very nice review by Bulldog
    5 4 Very nice

    I've moved houses a bit, and always installed pet doors. This door was the easiest to install and has been fairly reliable.

    security options - lock and a solid plate.
    easy for dogs to use
    easy to install

    lock sometimes fails (but the Texas heat does that, even to my deadbolts. I'm handy, so I replace the lock mechanisms myself. )when it fails, the locking mechanism locks the door.
    noisy - my dogs BURST through the door and bang them open, even in the middle of the night. Boston terriers are wacky that way; never do anything subtle; except sneak your sandwich.

    I replaced my first model with a larger model because I got a big dog. That's a testament to how pleased I am with the product.

    What I do not feel is a con but you should know going in is, there is weather stripping that will wear down. Easily replaced but my wife was annoyed until i replaced.

  • I LOVE THIS DOOR review by Kim from Downingtown

    This is the best pet door I've ever seen/had for many reasons. We currently have 2 XL dogs. This door allows them to go out on their schedule. It's weatherproof and air tight. Important in our Pennsylvania winters. It's durable - we had our 1st Plexidor for 15 year before my dogs, their dog friends, my extended family's dogs actually wore it out. It's easy to train puppies or dogs to use because it's "see thru". Timid dogs aren't as timid when they can see where they're going. Lastly, the weatherstripping is replaceable so if an air leak does develop - nose in the same place over many years - you can re-thread some new weatherstrip and you're good to go for many more years. I hope they NEVER stop making this door. Oh, and it's lockable - securely lockable. EXCELLENT PRODUCT! Thank you!

  • so very happy review by maidrobina
    5 5 so very happy

    Best thing we have done is put in a pet door. Our pets love it. We love it. They are in and out all day long. We never worry about them out in the heat nor cold. They are always safe. We have had the dog doors (large Size) and have had for nearly 4 years. The doors have held up well to 2 large dogs. We live in southern Ontario and have had extreme temps from 100 deg F in summer to minus 20 in winter and the doors keep the weather and wind outside. We were worried at first we would lose a lot of money with leaky doors so we purchased these doors as they seemed to be the best weather proof ones and they have lived up to expectation. There has been some wear on the weather strip around the doors edge but in 4 yrs of high use is very expected and it looks very easy to replace. I saw some replacement strip at the hardware store for about 20 can.dollars just cut to length stuff. I expect to replace in next 2 to 4 years. But weather strip is still working 100 %. we sit about 2 feet from the dog door in our kitchen and there is no feeling of the outside environment except when the dogs come in or out. But the doors swing very quickly shut so very minimal amount of outside air comes in so it is just momentary discomfort. The doors are easily cleaned. They get dirtier faster if your dogs are dirty-we often walk ours in the country and they get very dirty so we should clean weekly but since the doors are see thru we clean about once a month. OUR dogs absolutely love these doors. they love the freedom. We have some wild life in the area.. squirrels, raccoons too they have never come in the house - I was worried they might come in for dog food but never happened. bottom line these doors are worth their weight in gold. they have stood up to heavy use and don't waste any of our precious heat/air conditioning. only issue is occasionally the dogs will peak their heads/nose out and hold the door open to sniff, it's cute but we just say "in or out not open" they seem to get it.

  • Plexidor Pet Doors for Doors review by Moi
    5 5 Plexidor Pet Doors for Doors

    With 2 cats and 1 large dog I could not be happier with a Plexidor Pet Door. They literally go in and out the Pet Door day and night year around. Have had the same door for years by replacing the insulation one a year this keeps the pet door airtight. Awesome and durable product.

  • Worth every penny review by Shaunie
    5 5 Worth every penny

    We would definitely give this 5 stars! We paid a lot for this pet door and it has been worth every penny. In the past we had the PetSafe door with the flap that constantly wore out and it always let a lot of air in. We don't have these issues with the PlexiDor.

  • Great choice review by Jana
    5 5 Great choice

    In preparation for the arrival of my new puppy, I ordered the PlexiDor Pet Door. It is well built and provides the flexibility I needed for my puppy. She caught on quickly on how to use the door. I work long hours, so the PlexiDor has been my saving grace! Thanks for providing such a great product and service.

  • AMAZINGLY Bull Terrier Proof review by hugajudge
    5 5 AMAZINGLY Bull Terrier Proof

    I have 2 English Bull Terriers (they're a rowdy breed :-) ) These 2 like to run full speed across the house and hit the doggie-door at warp 6! I've had this door for 9 years now, no repairs, all original, and it is still as solid as the day I installed it.

    It holds closed in the wind, it stands up to Mid-Missouri's summer heat and winter sleet, it is the best money I could have spent.
    PlexiDor may be more expensive than those hardware store doors but my goodness, they pay for themselves in utility savings and durability.
    I'm getting ready to build a new house and I've already told the builder to make room for a PlexiDor. It's the first thing I thought of when I started planning the construction.

  • This is one awesome doggie door review by Crazy Dog
    5 5 This is one awesome doggie door

    we bought this doggie door for our 5-ton army truck ("CRAZY DOG") which we turned into a camper. we installed it in the back of the cab and allows the dogs (All 3 of them) to come visit us in the cab on long trips. it is durable, stands up to the beatings from the truck while off road and is very weather proof (I say proof and not resistant here too!) the lock is very well made, the doors are just awesome, and on hot days when we don't have the dogs we leave it unlocked and it provides vent path for cooling off the inside of the cab! ha-ha

    you are going to pay for this little work of art but its worth every cent! I wish we could attach a pic but I think we just about said it all above!

Plexidor Dog Doors


Plexidor Pet Door for Doors Demo



Tools you will need:

- Drill Level or Plumb Line
- 1/2” Drill Bit Jig Saw with a Wood or Metal Blade
- 3/8” Drill Bit Ruler
- Felt Tip Pen Center Punch
- Hammer Phillips Head/Flat Head Screwdrivers

Your Plexidor must be fitted with springs at the top and in a true vertical position or it will not work properly. Please check this with a level or plumb line.

1. See Owner's Manual for correct position of pet door.

2. Tape template securely to the INSIDE of your house door.

3. With a center punch and hammer make a firm indent through the template into the door at the center cross of the 12 holes (14 holes for Extra Large). Then remove template.

4. With a 1/2” drill bit, drill through your door to make the four corner holes (marked A), drilling right through the door. Ease pressure when breaking through the surface.

5. With a 3/8” drill bit, drill through your door in the same way as step 4 to make the four holes (marked B).

6. With a 3/8” drill bit, make the four holes (marked C), drilling only 3/4” deep.

7. With a felt tip pen and ruler, mark out on door the thick dashed sawing lines (marked D).

8. With a Jig Saw, cut along sawing lines.

9. Place pet door in position with springs at top. Spring mechanisms must be able to operate freely.


10. Use the four long 2” 10-32 machine screws to connect the interior frame to the 2 exterior pieces of framing with threaded inserts. The inserts should point towards the inside. Make sure the square edge of the exterior sides and exterior bottom pieces are towards the inside of the pet door. Do not over-tighten the screws. Test the pet door flaps to make sure they move freely.

11. Complete exterior frame by screwing the top gutter and the lower piece to your house door using the 4 small #6 screws.

Click below to expand:

This does come with a cover that you manually place over the frame. If you plan on using the security sheet often, you may want to consider adding a sliding track to your frame for convenience.

You can purchase a new set of locks and keys through the manufacturer.

This door tends to already perform better for insulation than other products. Because the flaps are held by springs, additional magnets cannot be added. The door as is, is capable of withstanding extreme climates and maintains strong resistance against wind.

First, unlike typical vinyl flaps, these are made of rigid acrylic. Thus, the flaps are practically chew proof. Because they meet in the flaps, these flaps have shown to be easier to push for smaller pets. The panels are also lined with weather stripping for draft control and weather proofing.

The Plexidor is a great option for installing in thin material. This self-framing door can be installed in materials 0-1.75" in thickness.

You will want to check if the issue is with the springs. You can purchase additional spring sets and/or replacement panels. Typically, if the panel is ajar after your pet enters and exits, the springs need replacing.

The steel security cover is manually screwed in over the frame.

The flaps are held in place via springs. Once your pet goes through the flaps, they are quick to shut. This gives the outside air little time to enter your home. Although these flaps are saloon style, they will not slowly swing back and forth for a lengthy time.

Each acrylic flap is 3/8" thick, which adds to the door's overalls sealing value.

Yes, tunnel kits are sold separately by the manufacturer, Plexidor.
