*measured from the ground to the tallest point of their back.

Your Track Height Adjustment range is based on the measurement of your door height from the lowest point of your track to the highest point. Each Dragon patio panel has a 3" adjustment range with your window track height approximately in the middle. The following adjustment ranges are available:

  • Short: 74 3⁄4" – 77 3⁄4"
  • Regular: 77 1⁄4" – 80 1⁄4"
  • Tall: 93 1⁄4" - 96"


CAUTION: If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.

IMPORTANT SIZING INFORMATION

The Dragon Pet Door’s two-piece flap is designed to tear away for your pet’s safety. If you pet door is not the right size for your pet, they may break off flap during normal use. Follow these sizing tips to help ensure that you are buying the right Dragon Pet Door size:

  • Check the Flap Height: You must measure your dog before purchasing a pet door. A large dog may not fit in a “large” pet door. The tallest point of your dog’s back should be at least 1” beneath the top of the flap. 
  • Check the Step-Over: Your pet should be able to over the bottom of the flap comfortably. If the distance from the floor to the bottom of the pet door (called the stepover) is too high, your dog’s paw may catch in the pet door’s U-gasket. It’s better to have a taller pet door that is lower to the ground than a smaller pet door that is too high up.
  • Check Your Entry/Exit Level: The inside of your home may be higher than the ground outside. This means that your door may have different step-over heights depending on whether you are indoors or outdoors. Try to use the lower level when picking your step over height. You can also even of the different levels with a ramp or platform. 
  • Reinforce Your Flap: Every Dragon Pet Door comes with instructions for how to reinforce the screws keeping your flap in place. If you are worried in any way that your pet may rip off the flap, we recommend preemptively reinforcing your flap. Note that doing so will negate the teat-away safety feature.

Step 1 Adjust the Spring-Mechanism

  • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.
  • Watch out, it might jump at you the first time!

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.
  • If you can't quite clear the track, try swinging in from the outside as the outside track wall may be shorter.
  • If the panel still doesn’t fit, see the FAQ for guidance.
  • Do not apply the weather stripping before test fitting the panel

Step 3 Apply the Weather Stripping

apply weatherstripping
  • 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.

    Parts

    • 1 Vinyl Panel Pet Door
    • 1 Weatherstrip Seal
    • 1 Center Post Weather Seal Draft Stopper

    Tools

    • Flathead screwdriver
    • #2 Philips head screwdriver
    • Non-metal hammer
    • Scissors

    Please read instructions & notes thoroughly before installation. If you need to adjust the step-over height, complete steps A-C before installing the panel in your track.

    Step 1 Assemble the Panel

    • Align the aluminum connectors extending from the bottom flap panel section with the top glass panel section.
    • Press the aluminum connectors into the holes at the bottom of the top glass panel section.
    • Ensure locking cover & height adjustment locks are on the same side!
    • Fasten the two panels together using the four flathead screws found in the panel packaging.

    Step 2 Loosen Height Adjustment Locks

    • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.
    • Horizontal Cross pieces have Edge Guides on each end. Carefully remove these parts and keep them together. This will help with assembly and orientation and when reassembling the piece.

    Step 3 Insert Panel Into Track

    • Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
    • If you can’t clear the track, try swinging in from the outside, as the outside track wall may be shorter. If the panel still doesn’t fit, see the FAQ for guidance.

    Step 4 Apply Weatherstrip

    • Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
    • Apply the foam weatherstrip seal by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides and trim to fit with scissors.

    Step 5 Place Panel In Track

    • Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.

    Step 6 Install the Draft Stopper

    • The center post weather seal strip (draft stopper) should be installed on the inside of the home.
    • It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel.
    • This strip prevents air from leaking between the sliding glass door and the stationary panel.
    • Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
    • Repeat step two to install the panel in your track.

    LOCKING YOUR DOOR

    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 Sliding Door Clamp Lock:

    The clamp has a thumb screw which 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.

    If you aren't able to use the lock that comes with the panel:

    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. It’s a fancier version of the classic broomstick handle in the track method!

    FREQUENTLY ASKED QUESTIONS

    What if my panel is slightly too tall?

    You can trim up to 5/16” 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.

    The dark area marks where you can trim:

    What if my panel is slightly too short?

    We offer height extensions that will add 1-1/2" to the top of the panel that you slide into the channel at the top. These are made from the same vinyl as the panel so the color will match exactly. 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 1-1/2", 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?

    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 Dragon Vinyl Slider Panel averages 34 lbs.

    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. Lastly 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 guide on how to measure your pet with tips on how to determine the correct size.

    Are replacement flaps available?

    Yes, you can buy Dragon replacement flaps.

    Where can I install the Dragon Pet Door?

    The Dragon Pet Door has multiple Installation options. You can install it in Regular Doors, as a Wall mount, Aluminum Sliding Doors, Vinyl Sliding Doors, Sash Windows, Vinyl Windows, and Horizontal Windows.

    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.

    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.

Lastly 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 guide on how to measure your pet with tips on how to determine the correct size.

    Are replacement flaps available?

    Yes, you can buy Dragon replacement flaps.

    Where can I install the Dragon Pet Door?

    The Dragon Pet Door has multiple Installation options. You can install it in Regular Doors, as a Wall mount, Aluminum Sliding Doors, Vinyl Sliding Doors, Sash Windows, Vinyl Windows, and Horizontal Windows.

    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.

    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.
