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 areas mark 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

What's the 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. For harsh climates, we recommend the double flap sash window insert

I want to get the large pet door for my dog, but I am concerned about a person fitting through it.

All Dragon Pet Doors come with a locking cover. This cover can be used to keep you doggy in. It also can be used to keep intruders from entering your home. It slides into the interior frame.

How do I know what size is best for my dog?

When installing the pet door you want it to clear the top of your dog's back by 1-2 inches, minimum. To give your pet the most comfortable pet door possible, make sure the step-over is less than 1/3 of your dog's height. You want the width of the door to be big enough to allow your pet to go through without touching the sides. Here's a pet measuring guide to help you out. 

Are replacement flaps available?

Yes, you can buy Dragon replacement flaps. You can also use the replacement flap to upgrade from a single flap to a double flap at any time if you find you need improved weather resistance. 

Can my small and large dog share this pet door?

Yes, but make sure to follow standard Measuring Guidelines. Make sure the size of the door is based off your tallest pet, but installed low enough for your smallest pet.

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.
