Parts

  • 1 Sash Window Insert with a Pre-Installed Single Flap Dragon Pet Door
  • 1 Foam Weather Strip
  • 1 Locking Cover

Tools

  • Screwdriver

Please read instructions & notes thoroughly before installation.

Step 1 Release Spring Mechanism

  • Loosen the width adjustment locks at the end of the pet door insert with a screwdriver. This allows the spring mechanism to move freely from side to side.
  • Watch out, it might jump at you the first time!

Step 2 Insert Into Window Track

  • Insert the spring adjusting cover into a vertical window track. Push into the spring mechanism and swing the opposite end into the opposite window track. Gently release.
  • Ensure that the pet door sits correctly in the window. See the FAQ for guidance if the sash does not quite fit.

Step 3 Apply Weather-Stripping

  • Once you have confirmed the sash fits, remove it from the frame.
  • Apply the foam weather-stripping by peeling back the paper and exposing the adhesive. Unroll it along the edge of the sash, pressing to ensure it adheres. Use scissors to trim the strip to fit the length of your sash. Apply to both sides.

Step 4 Lock Into Track

  • Place the sash back into the window, then tighten the width adjustment locks to lock it in place.

LOCKING YOUR WINDOW

For a temporary lock, place a removable wooden dowel or charley bar in either track above the window, shown here. For a permanent lock, install a screw in the track immediately above the window on both sides. You will no longer be able to raise the window.

FREQUENTLY ASKED QUESTIONS

What if my window is slightly too narrow?

The sash can be trimmed up to 34” in cases where it is a bit too wide to fit into the track. Remove the spring-loaded adjustment pieces using a #2 Phillips head screwdriver. Using a clamp and a flat surface, cut off the flanges using a jigsaw with a metal cutting blade. You can also use a hacksaw, though it is more labor intensive and you may end up with a less clean cut.

The dark area marks where you can trim:

What if my window doesn’t open enough?

Some windows will have stops that prevent them from fully raising up. In some cases, these can be removed allowing it to go up far enough to get the sash in place. You want to be careful when removing them, as it could damage the window or void the window’s warranty.

What if the track is too narrow for the pet door?

The spring adjustment pieces are slightly wider than the rest of the pet door, which may prevent it from fitting in the track. There are several potential solutions. One, you can trim one of the flanges off the spring-loaded adjustment piece, turning the "U" shape at the end into an “L". Alternatively, you can remove just one of the adjustment pieces with a Phillips head screwdriver and add shims for a snug fit.

You could also use a small piece of board in the channel of the adjustment piece, shown here. This board can be thinner and extend into the track giving the tension you need to hold it in place. Last option would be to install the sash using brackets to screw it into the track. Brackets would need to be made or purchased from your local hardware store.

What can I do if the track is wider than the pet door?

If the track is too wide to support the sash upright, you can use foam weather stripping or shims inserted into the track on the sides and/or bottom to fill up any of the gaps causing it to wobble. For a more permanent option, you can toe nail the sash into the framing with screws.

FAQ

Do you sell any replacement flaps?

Yes, we carry replacement flaps for our doors.

Can my large and small dog share this pet door?

Yes, but before you purchase, make sure to follow sizing guidelines and measure your pet before purchasing. Make sure the size of the door is based off your tallest pet, but installed low enough for your smallest pet.

How do I know what size will be best for my dog?

You want to make sure that the top of your new pet door clears your dog's back by 1-2 inches minimum. Make sure the step-over is less than 1/3 of your dog's height in order to ensure that the pet door is as comfortable for your dog to use as possible. Lastly you want the width of the door to be wide enough to allow your dog and cat to go through without touching the sides. Here's a guide on how to measure your pet with tips on how to determine the correct size.

I want to get the large pet door for my dog, but I am worried that a burglar could fit through it.

Every Dragon Pet Door comes with a locking cover. This cover can be used to keep your dog in as well as keep intruders from entering your home.

Is there a difference between the single flap and the double flap?

The double flap option provides increased insulation against the cold. Both options have magnets on the flap to keep the door sealed in wind.

Where can a Dragon Pet Door be installed?

First try

So far my cat is not a fan. He is used to a door that the flaps work in unison. He used that door right away without issues. These flaps are getting tangled between themselves as he tries to go in and out. Hopefully, he will get get the hang of it. Will update later.

High quality product

It is made very study and the looks of it is very pretty. I love the added window in the middle. Cats fit perfectly through it. The lock feature I use at night is very useful when they are inside. Thank you!

Easy to install

I have had a pet door in my window for years, it was homemade and seen it’s day, I ordered this one and am very pleased, it seems sturdy and has a nice clean look to it. Mine had a blemish on it and customer service was excellent. My dogs did have to get used to the window on one side, at first they were a little confused because the one we made was wood with door in the middle but once they realized that was not the door, they were fine. They are using it without any issues. I would give this a thumbs up, it doesn’t require any cutting into walls and if you want to take it out of window, no damage done. I am totally happy with this door.

Weatherproof but drafty when super cold

It took a while for my cat to get it but it works well. It is drafty but for what it is I think it’s pretty weatherproof. I did add more stripping and tape though.
