SECTIONAL ASSEMBLY

Step 1 Loosen the Screws

  • With a Phillips-head screwdriver, loosen the top two screws of the Dragon frame to make room for the glass section to fit inside.
  • No need to fully remove them!

Step 2 Connect the Sections

how to connect sections
  • Slide the flap section into the glass section. Make sure the locking cover is on the same side as the height adjustment locks on the glass section.
  • The section connectors will keep the two sections aligned.
  • Keep adjusting the flap section until it is fully flush with the glass section.
  • If you have a rubber mallet you can use it to tap them together.
  • Alternatively, pick up the panel and tap it on the ground on a soft surface.

Step 3 Fasten the Sections Together

how to fasten sections together
  • Fasten the sections by screwing in two connector screws each into the section connectors on both sides with the provided flat head screwdriver.
  • Tighten down all eight connector screws.

Step 4 Secure the Pet Door Frame

  • Retighten the two Dragon frame screws until the Dragon frames are flush with the glass section.
  • Press the nut into the frame to keep it from rotating.
  • Make sure not to overtighten.
  • Proceed with the regular Dragon panel Instructions below.

Step 5 Adjust the Top Piece

  • 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 6 Test-Fit the Panel

how to insert panel
  • Do not install the weatherstripping before test-fitting 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.

Step 7 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.

Step 8 Install the Panel

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.

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.
