Ideal "Fast Sash" Pet Doors for Sash Windows

This series incorporates a spring-loaded adjustment at both ends which provides for a total adjustment range of 5".

These doors incorporate a flexible, safe flap that ranges from a Small to a very Large Super Large size.

Note that the plastic locking cover slides straight up. So it's important that the window not have an overhanging lip that would be in the way.

Also, unlike the Ideal Cat Sash or Hefty Cat Sash, the flap must be centered or the locking knobs would interfere with the locking covers.

In addition to choosing an adjustment range that encompasses the full width of your sash window track, the track itself must be at least 7/8" wide to accept the pet door framing.

Frame color is white only. Single pane glass. Good value in a sash window pet door.

These units are built to order. Allow 3-5 business days to fabricate.

  • love it
    How do you rate this product?

    Perfect for our small dog and our fattest cat!
    Only downfall is heavy winds blow it open.

  • cat door
    How do you rate this product?

    We love it. The cats are getting used to it. It takes them a while since they are cats and we know how they are. Most go in and out with no problems as they have gotten used to the door that they can see through. Also had to get used to the new odor. We highly recommend this door to any cat who needs one.

  • Love this door
    How do you rate this product?

    Love this pet door. I got the door because one of my furbabies, Demo, was refusing to use the litter box inside. He wanted to use the great outdoors like his doggie brother and sister. This gives Demo the freedom to go outside and now I no longer have to clean up after him. I only give it 4 stars because the adjustable sides are a bit flimsy.

  • Life Saver!!
    How do you rate this product?

    We love our pet window! It give the dogs the freedom to go in and out as they need to! Easy to install and they learned quickly how to go in and out of it!

  • better than expected
    How do you rate this product?

    This door took 5 minutes to install and my dog learned to use it in another 2 minutes. Those 7 minutes have freed me from having to go home to let her out, or to clean up broken glass when she lunged at squirrels from inside the house...

    She's been using the door very frequently for about three months now and there have been zero problems with it. If only my cat would learn how to use it...

  • I'd buy it again!
    How do you rate this product?

    Great door. It took my 16 year-old daughter 10 minutes to install. My two dogs, an English Springer Spaniel and a Siberian Husky rough-house everyday, bolting in and out of this door. They slam into it and both try to fit through at the same time while they are play fighting. Still working great after three months of this. I like that it closes with a magnet vice a mechanized lock. The dogs learned to use it in two days, well it took the husky two days. The Springer took about 30 minutes.

  • Great!
    How do you rate this product?

    All 4 cats including the 18 pounder use the medium cat window. Easy to install and fits well.

  • Very Pleased!!!!!.
    How do you rate this product?

    Love it. I have large door. My dogs are Yellow Lab, Maltese and tiny Silky Terrior. They all use it with no problems. Very happy with this product. And it looks really good because of side windows.

  • Window Doggie Door
    How do you rate this product?

    We love our window Doggie door. It installed in seconds, took only a few minutes to train our dog and POOF he's outside enjoying the sun and the birds. We have floor to ceiling windows but if I lived in a house with higher windows I'd still use this product and use doggie stairs (like you use for a bed) so he could get in and out.

  • The best solution!!
    How do you rate this product?

    No where to install a pet door, so the window pet door was the perfect training neccessary.Andy knew exactly what to do right after it was installed. (which is super simple) My window is elevated a little off the floor, so I did have to create a "step" on the outside of the house......would highly recommend this product!

  • Great product
    How do you rate this product?

    It took me almost a year to finally spend the money for this pet door-I wished I had done it sooner! I have a very active Vizla who wants in/out/in/out/in/out , you get the picture. It took about 20 minutes of bribing her with treats to push through the clear flap. We did put a plastic tote on the outside so she didn't have a big drop off from the window sill. No problems with installation and pleased with fit in the window. We have had this door in place for at least 6 months of constant use and have no complaints. I highly reccommend this door for those of you get tired of the in/out game.

  • Excellent product!
    How do you rate this product?

    Good price.Easy to install.Quality merchadise. Our chuweenie wiil use her medium size dog door even when the people door is open!

  • Awesome door!
    How do you rate this product?

    I bought 2 for my dogs! One is in the front the other is in the back! The dogs come and go when ever they like! They fit perfectly and are very simple to put in! I added window locks at the top of the windows so no one can pull the windows open. I love these windows! My dogs do also! Unfortunately the UPS delivery man does not! Lol

  • GREAT!
    How do you rate this product?

    I bought one of these pet windows 4 years ago.

    I have moved and taken it with me. I love it. My cats love it.

    It's a great product. I have used it in 2 different windows and had no problems installing. It is durable and easy to clean.

  • Wonderful
    How do you rate this product?

    Love this window insert with dog door. Great addition to any home with a window and a dog.

  • Flap not so good
    How do you rate this product?

    Sorry not very happy with the dog door itself, the flap has a gap in it that runs all the way around and does not seal. Lets a lot of air from the outside come in. Other dog doors I've used utilize a flap that mats to the other that seals so air can't come in.

  • Love my door
    How do you rate this product?

    I am Max, the Dog. They got me this door to go in the window so I could get in and out when I want too. I love it! It is the perfect size for me. I have learned to hit it at almost full speed and it opens and snaps shut every time.
    It keeps the cold air out and seals right up. My people had it out of the box and installed in less than 5 mins. Took me even less to figure out how to use it, but I am smarter than they are.
    Bottom line, I love it. No more sitting with my legs crossed while they try to figure out I need to go outside or having to wait for commercials for someone to get up and open the door.
    Thanks for a great door for me!

  • Great dog door!
    How do you rate this product?

    We have been really happy with this dog door. Install was a breeze and we haven't had a single issue. It's been great having the dogs come and go as they please. No regrets whatsoever!

  • Love it
    How do you rate this product?

    I don't know why I didn't purchase this sooner. My cockapoo loves this door and uses it all the time. It was so easy to install and has been working great for months.

  • Life Saver!
    How do you rate this product?

    I bought this for my puppy as the getting up and down while I was recovering from surgery just wasn't going to be easy. She was potty trained all ready and learned very quickly to use the door. There were no accidents, she feels independent and can go out and bark at the cats and squirrels. I feel free of the up and downs and my recovery has progressed nicely.

  • Great dog door that offers peace of mind
    How do you rate this product?

    This was the second "fast sash" window I ordered from America's Finest Pet Doors. It arrived on time and is so easy to install. I have four dogs and need to keep them separate, so with the two sash doors I can give my dogs access to different yards. These pet doors fit great in the windows and are also easy to move if needed.
