ONE-PIECE PANEL ASSEMBLY
Step 1 Adjust the Top Piece
- Loosen the height adjustment locks at the top of the panel with a screwdriver. This allows the spring mechanism to move freely up and down.
Step 2 Test-Fit the Panel
- Insert the panel into the top track of your framing, push the panel into the spring mechanism and swing the bottom of the panel up and over the threshold into the rail at the bottom.

Step 3 Apply the Weather Stripping
- Once you have confirmed the panel fits, remove the panel from the track and lay it on its side.
- Apply the foam weather-stripping by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres.
- Use scissors to trim the strip to fit the length of your panel.
- Flip your panel around to apply on the other side.

Dragon Locking Details
Since you cannot lock your sliding glass door to your panel pet door, we have provided you with an alternative locking method to secure your home.
Installing the Clamp Lock
- This clamp has a screw that tightens by hand to prevent the sliding door from moving beyond the clamp’s placement.
- For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door’s raised track.
Locking the Flap
- The Dragon Pet Door comes with a secure locking cover to block access to the flap when needed.
- The locking cover is a great perfect for keeping pets inside at night, or for blocking access to the flap when you're away.
Alternative Locking Method
- A great alternative to locking your sliding glass door is a Charley bar or dowel in the track.
- Both work off the same concept—they block the slider from opening. When engaged you cannot pull the sliding door away from the pet door panel.
FREQUENTLY ASKED QUESTIONS
What if my panel is slightly too tall?
You can trim up to 3/4” off the spring- loaded adjustment piece at the top. This can be done by removing the adjustment pieces with a #2 Phillips head screwdriver and cutting down the flanges. Be careful not to cut too low or you will not be able to put the top back on.
The dark area marks where you can trim:
What if my panel is slightly too short?
We offer height extensions that will add 3/4” to the top of the panel that you slide into the channel at the top. These are made from the same aluminum as the panel so you can match the color.
You can also make your own extension out of nominal 1” wood (which is 3/4” thick), such as a 1x3, if you need more than 3/4" in height. Cut it to the same width as the panel and slide it into the channel at the top. Paint the wood to match your frame color. If the extension makes the panel feel unstable, you can secure it with screws.
What if the panel is wobbling slightly back and forth?
If your track is wider than 1” you can use small wooden shims or extra weather-stripping to fill in the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel.
FAQ
|
What's the difference between the single flap and the double flap Dragon panel for aluminum sliding glass doors? The double flap option provides increased insulation against the cold. Both options have magnets on the flap to keep the door sealed in wind. |
|
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 heavy are these panels? The average weight of the Dragon Single Flap Aluminum Sliding Door Panel is 27.6 lbs, making it easy to install and remove in a matter of minutes. |
|
How do I know what size to get for my pet? Here's a pet measurement guide to help you out. When installing the pet door you want it to clear the top of your dog's back by 1-2 inches, minimum. Make sure the step-over is less than 1/3 of your dog's height. Lastly, you want the width of the door to be big enough to allow your pet to go through without touching the sides, about an inch extra. |
|
Are replacement flaps available for this dog door for sliding glass door? Yes, you can buy Dragon replacement flaps. |
|
My sliding door track has a triangular guide rail. Will this pet door still work? Some sliding glass door tracks have a triangle-shaped guide rail instead of a cylindrical pencil rail running along the middle. This pet door panel has an arch along the bottom that is designed to sit on top of a cylindrical pencil rail. Pencil rails are shorter in height than triangular guide rails, which means that the pet door panel would wobble on top of it rather than sitting flush with the rest of the track. To accommodate the pet door panel you will need to build up the sides of the triangular guide rail so that the tip is less than ¼” tall. Please reach out to customer service if you have any questions about this process. |
|
Will this panel work if my sliding glass door has a buried track? Some sliding glass doors have buried tracks. Since this panel has an arch along the bottom that is designed to sit on top of a pencil rail, it will not be secure in a slider with a buried track without modifications. We recommend securing the panel to the track wall with L brackets or toenailing it to the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss your options for a buried track. |

I have a hurricane patio door. Will this pet door work for me? Hurricane door track styles vary widely, so they are case-by-case. Please reach out to customer service to discuss your pet door options for your sliding door. |
|
Will this pet door work with Anderson and Pella sliding doors? Anderson and Pella sliding glass doors have an inner track wall but no outer track wall. Additionally, the pencil rail is on the outer edge of the track rather than in the middle. Since this pet door panel is designed to sit between two track walls and on top of a centered pencil rail, it cannot be installed in Anderson or Pella doors without modifications. We recommend building out your track and using L brackets or toenailing to secure the bottom of the panel to the inner track wall. Building out the track means adding a piece of wood or vinyl that is the same height as the pencil rail to the space next to the pencil rail. This creates a flat surface for the pet door panel to sit on. Next, you will need to secure the panel to the track wall. To do this, you can use L brackets or you can toenail the panel into the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss this process or different options for an Anderson or Pella sliding door. |

Excellent. I would highly recommend this door.

Really good value. Fits well in patio doors with no gaps. The single flap works fine for mild weather, but double would certainly be better once it gets a little colder.
