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


  • 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.


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.


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 %" 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.
