Custom orders are final sale once built. They are essential in two situations:
While most sliding glass door track heights are in the three standard height ranges offered, some are not. In those cases, we can build a Thermo Panel 3e in a custom height to fit your specific dimension.
The second situation is when you have a side-sliding window. A sliding window is essentially a miniature sliding glass door, and you can install a custom height panel, provided the window track is at least 1" wide.

Since you cannot lock your sliding door to your panel pet door, we have provided you with alternative locking methods to secure your home:
Installing the sliding door clamp: 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.
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.
Semi-Permanent Installation:
You might choose to secure the panel in your track with screws. This can be done by drilling screws at an angle in the top and bottom tracks. We recommend doing this from the outside to minimize damage to the sliding glass door frame. One-way screws will prevent tampering or removal of the panel from the outside.
Stationary Panel:
Some stationary sliding door panels can be unfastened and moved over to one side so that you can install the pet door panel between the jamb and stationary panel.
Avoid damaging your sliding glass door by checking that your door can move and that you can reinstall it properly before trying to uninstall the unit.
You will still lose space in your slider to move through, however, you will be able to use your existing sliding door lock to secure your home. Installing your pet door this way is also great in that you already have an alarm system in place.
If your sliding glass door slides on the outside track, using an alternative lock might not be possible, so this allows you to still lock your door.
NOTE: You can do the stationary panel install with the regular spring actuator method – no need to screw it in.
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 piece with a #2 Phillips head screwdriver and cutting down the flanges. Be careful not to cut too low of 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 extension out of 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 hardware for the locking latch is preventing the door from sealing properly?
You might be able to remove the hardware, as in some cases they are only held in place with a couple of screws.
If you are not able to remove it you can try installing the panel on the stationary side as mentioned on page.
If neither of those choices works, you can try to shim the panel out so that it is even with the face of the lock. Depending on how far it sticks out you might be able to use a thicker foam weatherstripping or a small piece of wood between the panel and wall jamb.
My slider isn't closing evenly against the panel?
Your slider may not be level, which can happen in older houses. In that case, you may be able to adjust the wheels on the slider enough to line it back up. It will depend on your door, but you should be able to adjust a screw near the bottom of the door.
Turning the screw will adjust the wheels slightly. If the slider is level then it could be an issue with the metal height adjustment lock at the top of the panel. You can also use a rubber mallet to tap the curve into a straight line.
If the height adjustment lock is hitting the edge this can mean that the bottom of the panel is going further into the jamb that it can at the top. A gap appears that gets wider as you go down the panel. You can use wood shims or weatherstripping in the jamb to push out the bottom of the panel.
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 weatherstripping 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. You might also try semi-permanently installing the pet door.
The slider is on the outside track? How do I lock it?
This can cause an issue if you are trying to lock the door since the clamp lock, Charley bar, or dowel in the track won't really work. In this case, you can use a foot lock. The downside is that you have to drill that into the front end of the stationary panel frame as well as a small hole in the sliding door frame.
Depending on the handle of your slider, you might be able to put a Charley bar between the handle and the edge of the stationary. The slider would then push against the pet door and prevent someone from opening your door.
Alternatively, you can also try installing the pet door between your stationary glass and wall.
There is a large ste-down going out/coming in for the pet?
In this case, you can use a ramp or some small steps to minimize the height of the drop. You'll want the distance between the top of the flap and the ground to allow your pet to go through your flap without ducking or hitting their back.
What if I have an alarm system?
The alarm company might be able to come out and move the sensor for you. So instead of one part being on the door and the other on the jamb, you would end up having one side on the panel that matched up with the one on the sliding door.
As there are many different types of alarm configurations we would recommend that you always consult the alarm security company first to discuss your options.
Does this dog door insert panel work with vinyl sliders? Yes, the Endura Flap Thermo Panel 3e will work for vinyl sliding glass door so long as the track is at least 1" thick. However, for a snug fit and aesthetic look in your vinyl slider track, we carry the Vinyl Sliding Glass Pet Door as well. Read about the differences between vinyl and aluminum pet door panels here. |
Will a custom-made panel still have a spring-loaded design? Yes. The Thermo Panel 3e is built with a 3" spring-loaded height adjustment. When you order in one of the custom height ranges, you will be prompted for your track height. The patio panel will be built to a height that is approximately in the middle of this 3" range. For example, if you specify 40", your panel will be built to adjust from about 38" to 41" tall. We also have a sliding door pet door extension for cases where the panel may be slightly too short for their door tracks. |
How long will my custom panel take to ship? Note that the glass units for custom height orders take one to two weeks for delivery from the tempering plant and that we need about a week to schedule the assembly after the glass unit arrives. So delivery will take 2-3 weeks depending upon your location. |
How do I measure my door to get the correct height adjustment size? Measure from the innermost part of the bottom track to the innermost top part of the track. If there is a pencil railing, include that in the measurement because the panel straddles the railing. |
Does the Endura Flap Pet Door Thermo Panel 3e require tools for installation? You'll need a flathead screwdriver to adjust the top piece. Panels that ship in two pieces (sectionals) will need to be assembled with 4 hex screws and a hex wrench, all of which are provided for sectionals. The following panels ship in one piece: Panels under 80 ¼" with a Small, Medium, or Large flap. The following panels ship in two pieces: Panels over 80 ¼" with a Small, Medium, Large, or Extra-Large flap and panels under 80 ¼" with an Extra-Large flap. Shipping a tall and/or wide panel in two pieces saves customers on shipping costs since it can be shipped in a smaller box. |
Can an intruder remove the sliding glass dog door panel from the outside? No, the thumbscrews are on the inside of the sliding door pet door panel, so once installed, the Endura Flap Panel can't be removed without first loosening the thumbscrews from inside the home. |
Is this sliding glass doggie door good in a cold winter climate? I want something effective in our winter months. Yes, the flap on all of our Endura Flap Pet Door for Sliding Glass Doors has been tested at -40°F and it withstands winds up to 50mph. |
What Is the Step-Over? The step-over is the part of the sliding glass door dog door insert panel under the actual flap opening. Depending on the flap size purchased, the step-over can range from 3" to 7", so you can adjust it to any step-over within that range. |
How thick is the sliding door dog door insert panel? The Endura Flap Sliding Glass Door Thermo Panel 3e is 1" thick. |
What locking mechanism can I use for the Thermo Panel 3e? This Endura pet door comes with a C-clamp lock. Alternatively, a wooden dowel or Charley Bar can be used for additional security. |
Will there be enough room for me to get through after the panel is installed? The sliding glass door doggie door panel will take up some space in your sliding door track. See the "Overall Panel Width" column in the size chart. This gives the width of the panel, which is the amount of space that will be taken up. |
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. |
Can I install this into an up-and-down sliding window? We wouldn't recommend it. Instead, try the Thermo Panel 3e for Cats. |
Is there a way to permanently install this into my sliding glass door track? Yes, you can drill the panel into the track to keep it in place. If you are looking for a more aesthetically pleasing option, try the Pet Door Guys In the Glass model. |
What do I do if I have sliders that meet in the middle? You can install the panel in the middle of the track and anchor one of the doors to it, creating a single sliding door. |
Can I get the panel in more than one color? Our panels are only available in one solid color. However, the door and wall mounts are available with mismatched frame colors. |
