Height Adjustment Ranges

Custom Step-Over Options - These can be extremely important in properly fitting your pets. Especially if you have larger pets sharing with smaller ones, or older dogs that might not be a spry as they used to be.  You can purchase these panels with the custom step over on the Custom Ideal "Fast Fit" Patio Pet Door page.

Custom Height Add-On Extension - If your sliding glass door track is not accommodated by one of these height ranges, you can special order a panel with a custom made height extension to fit your track. The panel with the extension can be purchased on the Custom Ideal "Fast Fit" Patio Pet Door page.  If you already have the Ideal "Fast Fit" Panel, but it's too short for your slider you can also purchase just the Ideal "Fast Fit" Height Extension.

Replacement Flaps and Parts  - Can be found at Ideal "Original" Replacement Flaps or you can get both the flap and the plastic frame at Ideal "Fast Fit" Replacement Flap Assembly.

If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.



Ideal Fast Fit Patio Panel Pet Door

When you're looking for a "best bang for your buck" deal, an Ideal Fast Fit is the perfect solution. Affordable and functional, this pet door is lightweight and easy to install. The spring-loaded design allows you to securely place it in your sliding glass door track within seconds, and the clear vinyl flap opens easily for your pet to use to access your home.

Features of the Patio Pet door Insert

  • Single pane glass is lightweight for quick and easy install, and easy removal when necessary. 
  • Clear, vinyl flap is easy for pets to learn to use and push open.
  • Since this panel will not mate with an existing slider door lock, Ideal supplies a pin lock. This does require drilling holes, so if you're a renter and do not want to put holes in the slider, then we suggest using the old "broomstick in the track method" or a Charley Bar.
  • Solid magnetic strip at the bottom of the flap to help keep the flap closed when not in use.
  • Customizable options for the perfect fit for your slider and your pet.
  • Aluminum frame designed for sliding glass door tracks at least 7/8" thick.
  • 1 year warranty.

Perfect Time for an Ideal Fast Fit

  • If you are on a budget and want a doggie or cat door for your sliding glass door, a Fast Fit is the best choice.
  • For pets that may be timid or struggle with pushing through a heavier flap, the vinyl flap in the Fast Fit is easy to learn!
  • This is a great option if you need something temporary for a rental home where you can't drill holes in the track.
  • If you travel often and need a door that you can take in or out.
  • Great solution for storm prone areas where you need to be able to remove it quickly to secure your home.

Custom Options

Our step-over options allow you to tailor your pet door to properly accommodate your pet's size.  Custom height extensions can be added to your order should the inserts be too small for your sliding glass door. 

Check out our Custom Fast Fit!

Panels ordered with a custom stepover are NON-RETURNABLE as are the custom made height extensions.

  • Good product and customer service review by Rebecca
    5 5 Good product and customer service

    I am very satisfied with the pet door I purchased. It was very easy to install, and required no tools so I don't have to worry that it will damage the doorframe in the home we are renting. We do have a little insulation issue, but I think it is related to the doorframe itself and not the pet door. We were able to purchase more insulation strips and it works just fine now. I also received great customer service when I called several times in search for the right door for me. I would recommend this product and this company for future pet door seekers.

    5 5 Perfect for tall dogs

    My English Bulldogge/Boxer mix is 27 inches tall at the top of shoulder. The Lab is 24. Both are 13 inches wide. Insalled from floor to top of opening is 29-1/2 inches high. They go in and out this door perfectly without hitting anywhere. It was a quick study for them to master how it works. The customer service was amazing. Easy install. Thank you Courtney for your care to insure it got here quick! I hope this helps you compare your dogs size to fit this door, well worth it to know your babies are not locked in doors all day. 100 stars for pet

  • Poor weatherstripping design. review by Lyn
    5 4 Poor weatherstripping design.

    We recently purchased the medium sized white vinyl patio pet door . While the door works great for our boxer, we were disappointed that the while vinyl weather stripping was not one long piece but came in two pieces, causing an interruption in the length. Also, it does not hold it's shape, and it gets caught in between the actual door causing us to constantly pull it out to close the sliding glass patio door. In addition, there is not enough weather stripping for both sides (inside and outside) of the door.We would like to give this product a 5 star rating but for these reasons we feel obliged to give it a 4 star rating. This definitely needs improvement, especially since we paid over $200 for it. Now we have to figure out a solution for this flaw.

  • Great fit, easy to install review by Denise
    5 5 Great fit, easy to install

    I had a pet door from my mother, since we took her cat. It did not quite fit into the sliding door frame. I measured, ordered the right size door from PetDoors. It came promptly, I unboxed, slid it into the sliding door frame and 'Voila' -- done! I didn't screw anything in because I have bar on that door (we rarely use it). Easy as pie.

  • Love it! review by VALERIE
    5 5 Love it!

    Was looking for a doggie door I could easily install and remove and this one fits the bill perfectly. I have a Jack Russell and rescue Chi-Chi/Rat Terrier and they love being able to go in and out as they please. I used to keep the sliding glass open for them to out on the pool deck and then out those doggie doors, but the heat coming in was ridiculous. Living in FL I had to make a change. This doggie door is well made and super easy to install. Really, no tools. If you're on the fence, I highly recommend this doggie door.

    5 5 So easy and sturdy!

    I was a bit reluctant to shell out $300 for a dog door, but we have four huge German shepherds. I am so glad I made this investment. It was a cinch to install and seal, and our dogs haven’t budged it since we put it up a month ago. Worth the money.

  • Even better than last one! review by Lynn
    5 5 Even better than last one!

    I move this pet door back and forth between the runner for the screen door and the one for the glass door. It's very easy to do and makes it possible to adjust the placement to the weather and to fully lock the door. I have little dogs and there is a step down to my patio, but I placed a cement block outside the door and they hop up and in with ease.

  • Repeat Satisfied Customer review by CCNotInCT
    5 5 Repeat Satisfied Customer

    I purchased a pet door from for my apartment quite a few years ago now and was very happy with how it performed and held up over the years. My dog loved it too - he used to spend many a happy hour sitting on an ottoman on the patio surveying the neighborhood and having a grand old time. Fast forward to today where I am in a condo with a much taller yet still standard-sized sliding glass patio door and I decided to get a new pet door for the dog I have now. He is showing all signs of loving it just as much as his predecessor did and the patio pet door is the perfect color and fit. The quality has remained consistent. Thank you from a very satisfied customer and her delighted pooch!

    Very happy with purchase when we first got our puppy, we were told he would be able to fit through our cat door even when he got full-size . But he got bigger than they thought so we needed a little bigger door . We have been very happy with the cat door and how it looked in our patio door and this looks just as nice . The white trim is perfect and both the 30 pound puppy and five pound Yorky can get through it easily

    We were interested in a dog door we could install when we were gone from home so our dog could get in and out but be able to take out while we were home. This product is well made and installs in literally seconds. Weather strip made it fit snuggly to keep the cold and/or heat from escaping the house. Would higly recommend!

  • Perfect door for my very tall dog! review by Deborah
    5 5 Perfect door for my very tall dog!

    I have an incredibly tall mastiff that came from a dog meat farm in South Korea. She is very timid and afraid of a lot of things, so I was worried she wouldn’t be able to use a dog door because it might scare her. Well, I did t need to worry at all, because the flap is light enough that it doesn’t bother her when it touches her back, and the door is sturdy enough that when she runs into it, it doesn’t move. She is 120 pounds and the door fits her perfectly. I’m really happy I was able to find an extra large door!

    5 4 Not as easy to install...

    I unfortunately have a 60' sliding glass door and I had a heckuva time installing it. There wasn't room to "swing" it into place. It took a lot of manipulation to get the dang thing in. It wasn't the products fault but the super cheap sliding glass door that was installed by the builder. Now that I have it installed, I love it! I can leave my dog inside whilst I go to work and she can go in and out at her leisure.

    This was one of the smartest purchases I have made. Baxter comes and goes as he wants into his fenced back yard. If I am detained, i know he can go outside if necessary. My only complaint is that the sealing strip does not stick to the wood very well. I am not quite sure how to remedy that. I am sure there is a way.

    5 5 It made life a lot easier.

    I love the patio pet door. Our two labs can go in and out when they need to. No one has to get up to let them out then get up again to let them back in; over and over. They go out to play for a while, then come back in to rest. They go out to "potty', then they come back in independently, no more accidents inside due to owners not moving fast enough to open the door. Love it!

  • too small review by terry
    5 4 too small

    I was disappointed. The measurements are right but the door is too small for my dogs. They go through so fast they hit the top. I just wished it was more rummy for the size dog you recommend to use.

    Editor's note: Measuring your pet is so important, and we recommend the top of the flap to be at least 1 inch above the tallest point of the dog's back.

    5 5 Great Door, Works well

    I had a hard time finding a door tall enough to fit that wasn't costing me an arm and a leg. This was perfect, fairly easy to install and the dogs were able to acclimate to the door within 24 hours. It is a life saver for my carpets and wood floors! Price is great. Now I have a new dog which will require me to purchase a larger door. Ordering the new one in a few weeks once she is out of puppy stage and can "grow" into the new larger door.
    Might be a bit of a snag for the other shorter dogs, but they should be able to step over the 8" frame

    5 5 A Live Saver - Great Door

    I purchased this door with the low-height step over option as a gift for a friend with three dogs. The low-height option works great for her dachshund and basset hound; they can go in and out with ease. My friend absolutely loves this door because it saves her from having to constantly let in or out one of the dogs, not to mention the multiple times every night that she would have to get out of bed and go let out one of the dogs. It is worth every penny.

  • Not the quality I expected review by Very Large Dog
    5 2 Not the quality I expected

    Pet Doors was the only website I could find the size I needed. So I was left with no choice. I figured all doors are the same right? Wrong. The door is so thin, and does not fit into the door track well at all that it shakes every time my dog goes in and out. Not to mention the air flow that comes in between the door, the slider and the top and bottom. Also, because i assume this door is the same one they use whenever you ask for different step over options, that is is in pieces, and again, since it does not fit within the door very well, it is separating at the "seams". I have had this doggy door for 3 months and am frantically looking for another one before the cold weather hits. Would I buy from again, NO!!

Neither my husband nor myself are very handy but we got it in fine. I did go up to the auto supply & purchased more insulation as we needed more, easy deal. I would buy again. One other thing.. The delivery guy dropped it off at our neighbor's house in error, just in case FYI

    5 5 So Easy

    We had one of these pet doors in our previous house so got another one when we moved here. It was so easy to install I didn't need my hubby to help. One dog used it immediately, the other had to be coaxed with treats over several days but now they both hop in and out without thinking about it.

  • Decent product review by Sophie's mom
    5 3 Decent product

    Installation was very simple after I cut about 1/8 inch off the top metal piece so it would fit in the tracks of my 96" slider. My 30lb black lab puppy took to it quickly and loves running in and out at full speed. Gaps between the pet door and the slider are a problem, but weather stripping has helped minimize those. Not exactly what I had hoped for, but it has been workable.

  • Easy to Install, Great Product for the Price review by kshgw
    5 3 Easy to Install, Great Product for the Price

    I would say that this was very easy to install, as long as you don't mind some minor gaps and it can fit between the lock in your slider track, since it doesn't use the lock feature. It's not the most secure installation. A burglary could probably get the sliding bolt to pop out if he had enough time or just break out the door to squeeze in. However, it works well for everyday use. I wish the sizing was more uniform with other doggy doors. I had medium doors at my old house, so I ordered a medium without looking carefully at the opening size. The opening is not big enough for one of my dogs, who used to be able to fit through my old medium door. Otherwise, I'm very happy with the purchase and it was much cheaper than other doors.

    Why? Because nobody could figure out how to intall them. INCLUDING ME, a LICENSED CONTRACTOR FOR 40 YEARS!
    Of course that does not mean I know everything. I will also be returning this item.

  • Great review by Old English Sheepdog
    5 5 Great

    100 lb Sheepdog, the Super Large works best. Although we were replacing another door, She did not like the smell, we left up with the old door in place for a month before she finally was able to use the new one. Now she loves it, it is quieter than the old flap.

    One recommendation is a wide strip(2") to work with slider, we have an older house that has settled and the opening is not correct as it should be. Some sort of accommodation would be great.

    5 5 Great pet door, easy to use.

    We bought the 96"+ medium flap door for when our friends and family bring their dogs. It takes on a few minutes to put in or take out....and stores easily in our garage. We're thrilled that we found it.

  • Not what I expected! Just a thin Pane. review by Rob
    5 1 Not what I expected! Just a thin Pane.

    This door is about one third of the width of the slot it is fitting into (standard slider slot). I had to buy several rolls of the rubber molding stuff that is sticky on one side. I added six layers to the sides, top, and bottom on the outer face of the door to fill the giant gap between the door and frame. It also does not attach to the slider door, or the door lock, or the latch on the frame side. It is simply just a thin pane of metal and glass that buts up against your door. You have to find ways to fill the gaps and cracks. Also allows anyone to easiyy brake in. The weather gap strip they sent fell off within a coupe days and didn't do much anyway. You have to stuff things in the gaps between the window pane openings on both sides to prevent air leakage. The pane of glass is also thin and accumulates a lot of condensation on colder days. It is not very warm. The flap just blows around with a slight breeze, and never hangs straight. Always cold air blowing right in.

    ed. note - There is no such thing as a 'standard' track dimension for sliding glass doors. Patio pet doors are traditionally built on the thin side so as to fit in any.

    5 5 Quality product and as easy to set up as the description says

    What I love about this is the ease of set up and removal. We use just for vacations or long days out . It's a bit Narrow though for our dog and I wish the width expanded with the height. She makes it through and it's excellent quality

  • Poor Customer Service - Do not pay for 2 day shipping review by John
    5 1 Poor Customer Service - Do not pay for 2 day shipping

    Needed the door in 5 days in order to take an overnight trip. Paid $42 for 2 day delivery by FedEx. Now, 6 days later still no door. Called customer service and they said the item left their warehouse within 2 days, that is 2 day shipping!!! I told them I no longer needed the door since it is late, what if I do not accept it when it finally arrives? She said, oh don't do that because FedEx will return the shipment using 2 day delivery and I will be charged $42 for shipping plus a return fee. Duhhhh - 2 day shipping is not what it use to mean

    ed note - Some items, including this one, are shipped direct from the manufacturer. In this case it did ship 2 day air but the mfr took two days to ship. We ask on the cart page that customers with specific delivery needs contact our customer service department which will expedite the shipment if possible or at least alert the customer to the time to expect the delivery.

  • Schnauzer endorsed! review by sanity saver!
    5 5 Schnauzer endorsed!

    A pet door gives everyone peace of mind! The dogs seem to relish making their own decisions about when to go out in the backyard. And at night how nice to not have to get up and open a door! They figured it out immediately! No one with a cat or dog should hesitate adding this convenience to their routine.The door looks great, fits so tightly against the sliding panel that no one notices it. GREAT product!!!!

  • medium flap pet door review by Lia
    5 2 medium flap pet door

    flap is too small, even when I measured dogs appropriately. Unless there is a fire and the dogs are super motivated to get out of the house they dont use it. Surprised there isnt a large as the sizing goes from medium to extra large, not good for a 35 lb dog, who is a little squeezed for the medium. Now it just sits there. Buy a size larger when in doubt anf dont use their measuring advise.

    ed. note - The Fast Fit 'XLarge', at 10 1/2" x 15", would be a 'large' by any reasonable standard.

  • LOVE LOVE LOVE! review by Kristin McDonald

    I have a home office (with a big sliding door) which I share with one of my employees. I also have 2 big labs who love that they can hang out with us... BUT, they drive us crazy by always wanting to in, out, in, out, in, out. It got to the point where I bought a pedometer to see how much I was walking per day just letting them out! I looked into doggie doors, but did not want a permanent hole in my wall. I founds some Patio Pet doors but they could not accommodate the XXXL size I needed for my dogs. The, I found this miracle. First, it's not permanent. Second, it came in a Super Large size, and third, it was super easy to install. This patio pet door has truly increased my productivity! It's a life saver... I love, love, love it. It works fantastic. My two big guys are not gentle on anything, and the door has withheld them racing in and out like bulls. Thank you, and YES. I highly recommend this product!

  • Second Patio Fast Fit Door and love both review by Sandie
    5 5 Second Patio Fast Fit Door and love both

    I lived in a townhouse with taller sliding doors. Bought the larger one for my 3 lb. pet bunny, Roger. It was so easy to put up and just perfect. Roger learned how to use it FAST but thought he was too good to use that door so a bit of a conflict with whose the boss in the house. Then I moved to another home and the doors were shorter so bought another door for Roger so we could argue over his using it, and it was just as easy to install. The customer support is outstanding. I have told many friends and acquaintances of this product and to order it only from this website. In a 5 star rating would give it 5 stars.

  • Good value but need engineering improvements review by Oz
    5 3 Good value but need engineering improvements

    I ordered the door after extensive serch. It arrived on a timely basis. It would have been better if the quality of workmanship was better. Rubber seals in a few areas were separated from the frame & glass. I had to fix them. It would not fit into the tracks per instructions. I needed to deviate from the instructions and had to install rubber seal to close the gaps. Because the glass is thin in Florida climate more power will be used for the A/C.

  • Love this door. review by Sam
    5 5 Love this door.

    Great product. Wish we would have ordered the Patio Pet Door six months earlier. We had gotten two puppies and were having a hard time potty training them. They did not give us any signs when they wanted to go out. Since installing the patio door there has not been one accident. After the door was installed it took 2 minutes to train the dogs on how to use it. We ordered the extra large and my standard schnoodle (70 #) has no problem with the opening. If you have a dog you need to buy this product.

    5 5 Excellent

    I didn't want to cut a hole in my wall, and a friend told me about Patio Pacific pet doors. Installed my pet door panel in about 2 minutes. My only concern was the flap size, it is smaller than my extra large pet door at my other house, after reading your customer reviews, one customer had Great Danes getting through the panel door!! My Saint Bernards clear it without a problem .... A great product, does exactly what it claims, I'd buy another one in a second, Happy customer for life

    This is perfect for us. Took exactly 5 minutes to install and now my two dogs can go in and out as they like. The house also stayed warm even when the evenings went down to the 30s. I wasn't sure it would be rugged enough, but my two 90lb labs haven't phased it even though the young one likes to run through it at full speed.

  • Darth (Malamute) Thanks you review by Darth's mom
    5 5 Darth (Malamute) Thanks you

    This door changed our entire house-hold. My dog is over 3' tall at the shoulder, and about 1' wide during summer. In Winter this dog gains his winter coat so we remain hopeful he will still fit through the door

    We ordered the XL door, and it's a bit tiny, but Darth thinks it's the grandest bestest thing EVER that the tiny townhouse back-yard now belongs to him entirely.

    I took a sausage, got him all exited, then threw the sausage through his new door into the backyard, lifted the bottom of the flap to show him go, and out he went. Then I held a sausage inside and in he came to get his sausage. That was that. He Loves the door, and we love the freedom it offers all of us while keeping the house toasty and warm

    Thank you PetDoors!

Quick Video on Installing the Fast Fit


1. Release automatic height adjustment by turning knobs located near top of panel counter-clockwise and pressing. Height adjustment panel should fully extend upward (pull up on panel if necessary).

2. Open sliding glass/screen door.

3. Insert Fast Fit with knobs facing inside. Place top edge into top track of sliding glass/screen door. Lift up and swing lower portion of panel onto ridge in sliding glass door (or screen door).

4. Slide Fast Fit against doorjamb and make sure that top is fully extended, not tilted to one side, and bottom of panel is on ridge in bottom track.

5. Hand-tighten knobs by turning clockwise to lock Fast Fit in place.

To permanently install the Fast Fit, you may screw through the aluminum fins that protrude on the existing frame of your door. Drill through the fins into the Fast Fit. Install two screws in the top and two in the side by the bottom of door. Do not put any screws into the frame by the glass of the Fast Fit as breakage may occur.

Optional permanent placement for fixed panel sliding door. Remove screws that hold fixed glass panel in place and slide over. Insert the Fast Fit panel between stationary panel and it's jamb and re-fasten fixed glass panel.

Installing Security Lock (Optional)

1. With sliding door in closed position, place lock in desired location with bolt in the retracted position, pointed toward the sliding glass door or stationary window rail. Leave approximately 1/8" clearance between bolt tip and aluminum rail (Figure 5).

2. Holding lock firmly in place, mark screw holes and center of bolt in rail of sliding door or stationary window.

3. Drill two 5/32" holes for mounting screws and a 3/8" hole for locking bolt. Caution: Do not drill into glass.

4. With sliding door in the closed position (with Fast Fit installed), mark position for second set of holes.

Repeat above instructions. Caution: Do not drill into glass.

In Depth Ideal 'Fast Fit' Installation

Click below to expand:

Generally yes. The big difference between the two types of sliding glass doors is the thickness or width of the track. As long as your track is at least 7/8"wide, this can fit your patio door. If you have a taller sliding glass door, we recommend that you either add shims or toenail the panel in for added stability. If you have concerns you can email with some photos of your track and we can let you know.

The patio pet door insert doesn't, it is meant to be fairly easy to install so you can take it out if you need. Although you will need tools if you want to install the locking mechanism as it requires drilling holes into the frame of your slider. You can avoid this by locking your slider against the panel using a Charley Bar or dowel in the track.

The Fast Fit panels will not be able to lock into an existing slider door, as there are so many types of door locks they cannot mate with the dog door insert. This door includes a pin lock or you can go with a dowel in the track or Charley Bar.

When the pet door is installed, you will lose some space to walk through. To make sure that you have enough room, we recommend that you check the Overall Width of the size that you want, especially when purchasing this panel in the Super Large flap size. If you are looking for an option that won't obstruct the use of your sliding glass door, we would recommend the Pet Door Guys - "In The Glass" units.

We recommend that you measure your pet using the methods described in this video.

Yes. The flaps are light enough for small pets to push. We recommend a custom lower step-over height to make it easier for the shorter pet to use. The flap should also be large enough for the tallest pet to use without bending down.

The flap will likely blow open with mild wind since this is a more economical doggy door. When more extreme weather occurs, we recommend that you place your locking cover over the pet door or remove the panel.

Unfortunately flaps are not interchangeable between pet doors. In order to get a more wind resistant flap, you would need to change out the entire unit.

No, the Fast Fit does not have an adjustable step over. You can get a custom step-over. Keep in mind that the custom step over cannot be adjusted once built, and it does make the item non-returnable.

Yes, this door does come with a black draft stopper and a black foam weather strip. You can order one in White here, but it would be an additional cost.

The fast fit aluminum pet patio door is 7/8" thick.

A cat could use this door, but the Ideal "Fast Fit" Sliding Glass Cat Doors is made specifically for cats.

Yes, the Ideal Fast Fit Flap and Frame Assembly is available for purchase. Please make sure you are ordering the correct logo for your specific panel. If you no longer have the original flap, you can figure out what logo you have a couple of other ways. You can measure the entire width of the panel, as these measurements changed when the manufacturing location did. Another option is to unscrew the frame from the patio panel, if it's one piece that screws directly into the sides of the aluminum frame, it's an old style rectangular logo. If the frame is two pieces that screw into each other (not the metal panel directly) than it is a new style round logo. If you still have the original flap (plastic frame), you may be able to figure out which flap and frame you need by looking at this page.

Ideal does offer a height extension, but you can also make up for slight height issue by sliding a piece of wood in the top channel that is cut to size. This should give the panel enough tension at the top to hold it in place.

You can actually trim up to 3/4" off the spring load at the top. It is 1/8" in thickness, this is done with a jigsaw using a metal cutting blade.

No, the flap has a magnet bar across the bottom. Additional magnets cannot be added.

No. It is designed to fit in the track of your slding glass door, not the screen. Here a link to our page with screen sliding door options:

The budget sliding glass door pet door insert we recommend is the Ideal "Fast Fit" Patio Pet Door.

The Ideal "Fast Fit" Patio Pet Door is a dog door insert for sliding glass door that is available in Brushed Aluminum which is a silver color.

The Ideal Fast Fit doggy door for sliding doors has minimum height of 75" but can be trimmed down to 74". This will not work if your sliding glass door has a track wall on both sides. If it does you will need to order a Custom Height Endura Flap Pet Door at this link:

The sliding glass door pet door insert we recommend for renters is the Ideal "Fast Fit" Patio Pet Door panel due to its no-tools installation and removal and lower cost.

We recomment the Draft Stopper. It will fill in the gap between the operational panel and fixed panel of your sliding glass door.

Yes! the doggy door insert we recommend is the Ideal Fast Fit Shorty pet door. It installs without tools and fits tracks 75-77 3/4" tall.

Yes. It uninstalls as easily as it installs.

You can add a custom made height extension to make it taller. If you're buying a new Fast Fit you can go to this page: If you already have a Fast Fit you should go to this page: to buy the Height Extension only.
