Choose the range that your track height falls into and when ordered you will be asked to give the exact height of your slider track inside very top to very bottom. In each case you will have 3" of height adjustment with the height you specify approximately in the middle of that range. The ranges are:
- Under 74 3⁄4"
- Between 80 1⁄4" – 93 1⁄4"
- Over 96 1⁄4"
Most sliding glass doors will accommodate the three-panel sizes offered. However, if our standard panels do not match your door size, we can build a custom Dragon Patio Pet Door for you. We can also custom make a panel for left-to-right sliding sash windows as long as the window track width is at least one inch. Custom height option may take up to 4 weeks to special order the glass and build the panel.
The panels have a 3-inch spring-loaded height adjustment, so if you request a 40" panel, the panel you receive will adjust from 38" to 41" inches.

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.
