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. 

If you have any questions about which size pet door your pet needs, please contact our team of pet door experts for guidance and recommendations.

Installation Instructions

Parts

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

Tools

  • Flathead Screwdriver

Please read instructions & notes thoroughly before installation.

Step 1 Release Spring Mechanism

  • Loosen the height adjustment locks at the end of the pet door insert with a screwdriver. This allows the spring mechanism to move freely up and down.

Step 2 Insert Into Window Track

  • Before applying weatherstripping, 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.

Step 3 Apply Weather-Stripping

  • Once you have confirmed the panel fits, remove the panel from the track and lay it on its side.
  • Apply the foam weatherstripping 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 the panel around to apply on the other edge.

Step 4 Lock Into Track

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

LOCKING YOUR WINDOW

Since you likely can no longer use your window’s original lock, we have provided you with an alternative locking method to keep your home secure.

Installing the track clamp:

This clamp has a thumbscrew that tightens by hand to prevent the sliding window pane from moving beyond the clamp’s placement. For windows manufactured with the slider on the inside track, the lock can usually be installed on the raised track.

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

A great alternative to locking your window 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 pane away from the pet door panel. If there is 15” or more of space for the sliding pane to move, a Charley bar will work. If there’s less, a dowel is necessary.

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.

top

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 %" 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.

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.
