Still don't know which flap size to get? Here is a measurement guide to help you out

Height Adjustment Ranges

  • B- Shorty 75" - 77 3/4" (additional cost)
  • C- Regular 77 5/8" - 80 5/16"
  • E- Tall 93 3/4" - 96 1/2" (additional cost)

Step-Over Options - These options can be extremely important in properly fitting your pets. They are offered as drop-downs after the size, height and color choices are made.

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 and it will come with a height extension.  If you already have the Ideal "Fast Fit" Panel but it's too short for your slider you can purchase just the Ideal "Fast Fit" Height Extension.

Replacement Flaps and Parts You can get just the replacement flap at Ideal "Original" Replacement Flaps or you can get both the flap and the plastic frame a 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.

Wondering how to measure your track? Review our Track Measuring Guide.

The maximum over-all height you can achieve in this manner is 110-½," and the tallest the extension should be built is 14." However, it can be made to 16", but the manufacturer suggests that you would then semi-permanently install it for stability by drilling the panel into the slider track. The height extension is built to your custom dimension, it is not returnable, though the panel is (provided you haven't ordered any other custom feature like a custom step-over).

Ideal Fast Fit Patio Panel Pet Door

When you're looking for a "best bang for your buck" deal, an Ideal Fast Fit patio pet door 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 Ideal Fast Fit

  • Single pane glass is lightweight for quick and easy install, or easy removal when necessary. 
  • Since this patio pet door insert 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.
  • Clear, vinyl flap is easy for pets to learn to use and push open.
  • 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 pet 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. (See the drop-downs after you choose flap size, adjustment and frame color. If you need help choosing the right size, see our page on how to measure your pets.) Custom height extensions can be added to your order should the inserts be too small for your sliding glass door. (Custom orders are not returnable).

    The support from your staff was important. The help with purchasing and installation was solid. The kindness was tangible. I am an old woman and wanted reassuring. The two young men across the street installed it easily. Thank you

  • Not beach worthy review by Pam
    5 3 Not beach worthy

    Well built door, great customized height for all my cats and dogs to use. Unfortunately, door faces the beach and is not as air tight as I would like it to be and the flap does not stay closed. And it doesn't fit in the hurricane sliding glass door without additional adjustments and weather stripping. All my animals are old and was worried that they couldn't open the flap that was rated for stronger winds.

  • Small means small review by Becky
    5 4 Small means small

    The height and width of the door works great but the flap opening for our dog is very, very small. Since she weighs only about 14 pounds I thought a small size would be sufficient. She definitely could use a medium but since the product is a “custom“ size it can’t be returned. Would absolutely love if it could be exchanged. The flap size would be my only complaint. Order came in a timely fashion and works well with our patio door.

  • 5 stars for a perfect and easy instalation review by Murl
    5 5 5 stars for a perfect and easy instalation

    This door fits great. Dogs love it. I have one very short legged dog and two german shepherds. I bought the xxl flap for the door and the german shepherds have to stoop about a 1/2 inch to get through it but they are getting used to it. Love the clear plastic flap.

  • Good overall, not very secure. review by Kris
    5 4 Good overall, not very secure.

    This is a relatively inexpensive door for a hard to fit space. We have an extra tall ceiling and couldn't buy the standard size. They cut to fit an extra panel for the top that looks the same as the glass door below. It is not an overly secure. I wouldn't put it on a house or first floor apartment unless you secured it better. We are on the 3rd floor, so that was ok. We use a stick in the door since you can't lock the patio door now. We did need to get extra weather strip foam because there was a definite gap due to screws in our patio door. It was inexpensive and easy though. There is still a bit of a draft. I wouldn't use this in cold climates.

  • Great product Just as advertised review by Bart
    5 5 Great product Just as advertised

    We moved into a Condominium with 9 ' sliding glass doors. Our cats access the balcony and hang out. It was impossible to find an appropriate cat door until I ran into this Company. Expensive but fits perfect. You get what you pay for... Typically and in this case

  • great option review by Barry
    5 4 great option

    Great work around for custom height doors. it was easy to put in but I expected it to be one piece. Instead it comes with a panel to put on top of it and it came in a normal box. Fits well and feels secure in my patio frame

    ordered a custom length pet door and it worked perfectly. No tools, great fit. You may need to to buy some alternative weather stripping for a good seal. I would give it a 9 out of 10.

    Good product and well made. My hound loves the easy access to the backyard through the right sized door. The optional lower step over height is great to accommodate my toy dogs as well as the larger hound.

  • A Live Saver - Great Door review by Robert
    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!!

  • We all are loving it! review by Dog Momma
    5 5 We all are loving it!

    We had a hard time finding a tall door for our slider. Luckily, we did find one that is functional & aesthetically pleasing. I love that I can see out of it & it looks like it belongs. 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

  • Great pet door, easy to use. review by Lin
    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.

  • 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!

    5 5 Ideal "Fast Fit" Patio Pet Door

    Love the Pet Door. I had special height restrictions due to "ahem" overly large but short beagles. The door is perfect for both my smaller beagles and the chubby ones. Will definitely buy from America's Finest Pet Doors again!!

  • 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.

In Depth Ideal 'Fast Fit' Installation

Click below to expand:

Yes - you get the regular panel with the height adjustment range that is shorter than your custom height as well as the custom-built extension panel that allows the door to fit the height of your track.

It's not. We have just combined the two for your convenience. The prices are exactly the same as well.

As long as the panel does not have a custom stepover, you can return the panel portion w/ the pet door, but you will not be able to return the custom height extension panel.

Calculate the height extension needed for a given track height by subtracting the maximum height of the adjustment range of the panel you've chosen from the measured height of your sliding glass door track and then add back 2-1/8".

Aluminum - if you have a vinyl track, the Ideal brand has the VIP and VPP models available. However those will not offer any custom heights outside of the listed adjustment ranges.

Ideal panels are best suited for temperate climates where insulation is not a vital factor when choosing a pet door.

No, the Fast Fit does not have an adjustable step over. However, 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.

The FastFit frame is 7/8" thick.

The door comes with a pin lock you can install. Alternatively, you can purchase a Charley Bar for added security.

Yes because the CUSTOM portion of this product is the extension panel that is built specifically for the height you need. So the box should contain the panel and the patio door extension.

Then you could go with the 75 inch patio pet door height option, and if necessary you can trim the flange at the top about 1 inch to be able to get it up and into your track.

Most are made from aluminum and glass. In rare cases for small extensions they are all aluminum.

You can trim up to 1" off the top of the Ideal Fast Fist.

Most are made from aluminum and glass. In rare cases for small extensions they are all aluminum.

This Ideal FastFit is a temporary pet door for sliding glass door and takes a few minutes to install or take out. The more you do it, the easier it is.

Yes, it can be done. Please call (800) 826-2871 x2 for a custom order. The other option is to order the small flap (soft vinyl) on the Custom Ideal "Fast Fit" Patio Pet Door.

Yes. Calculate the height extension needed for a given track height by subtracting the maximum height of the adjustment range of the panel you've chosen from the measured height of your sliding glass door track and then add back 2-1/8".
