Here is a measurement guide to help you out. Wondering how to measure your track? Review our Track Measuring Guide.
Track Height Adjustment range is based on the measurement of your door height from the lowest point of your track to the highest point. Each Custom Endura Flap Thermo Panel 3e has a 3" adjustment range with your window track height approximately in the middle. T
Custom Height Minimum & Maximum Heights:
| Model | Minimum | Maximum |
|---|---|---|
| Small | 35" | 120" |
| Medium | 42" | 124" |
| Large | 48" | 130" |
| Extra Large | 46" | 134" |
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 Thermo Panel 3e 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. If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.

Lock Details
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.
Other Installation Options
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.

How to Adjust the Magnet Strength on Your Endura Flap
How to Adjust Your Stepover
FAQ
|
What is the thickness of the panel? The patio pacific endura flap thermo panel 3e is 1" thick. It is only thick enough for a single flap, not a double flap. |
|
Does this panel work with vinyl sliders? Yes, the endura flap 3e is compatible with most vinyl sliding patio doors for a vinyl-pet slider that matches your existing track. At 1" thick, it is thicker than most aluminum panels, so it will fit better in a vinyl track. The track width may not line up exactly with the panel, but it is only an issue with the aesthetics, not functionality. |
|
Does this keep mice, rats, and other pests out? This is a manual door, so there is no guarantee that critters will not get in. However, the Endura Flap has incredibly strong magnets that are hard for small critters to push through and get in. |
|
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. |
|
What do the Step Over Range dimensions mean? The step over is the part of the panel under the actual door opening. Depending on the flap size purchased, the stepover can range from 3"-7". This means that you can adjust it to any stepover within that range. So if you have a puppy, you can keep adjusting it as he/she grows. |
|
Will there be enough room for me to get through after the panel is installed? That depends on how wide your sliding glass door opens and how wide the panel you purchase is. Those dimensions can be found under the "Overall Panel Width" column. |
|
Can an intruder remove the Endura Flap dog door for slider from the outside? No, the thumbscrews are on the inside of the panel, so once installed, the Endura Flap Panel cannot be lifted out and removed without first loosening the thumbscrews from inside the home. |
|
What locking mechanism can I use for the Thermo Panel 3e? You'll install the included clamp lock. Alternatively, the Endura dog door/cat door for sliding glass door can be secured with a Charley Bar for added security. |
|
Does the Endura Flap dog door sliding door come with locking covers for security? Yes, these dog doors come with locking covers to ensure safety for your pet and home. Endura Flaps have locking covers that slide over them on the side facing inside your home and are made of sturdy, heavy-duty ABS plastic. Unfortunately, they cannot be used on the outside of Endura Flap Panels as an alternative. |
|
Do the Endura Flap panels require tools for installation? All panel sizes will require a flathead screwdriver for the height adjustment locks. 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. |
|
Is this door good in a cold winter climate? I want something effective in our winter months. Yes, the Endura Flap has been tested in -4°F. |
|
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. |

Here is a measurement guide to help you out. Wondering how to measure your track? Review our Track Measuring Guide.
Track Height Adjustment range is based on the measurement of your door height from the lowest point of your track to the highest point. Each Custom Endura Flap Thermo Panel 3e has a 3" adjustment range with your window track height approximately in the middle. T
Custom Height Minimum & Maximum Heights:
| Model | Minimum | Maximum |
|---|---|---|
| Small | 35" | 120" |
| Medium | 42" | 124" |
| Large | 48" | 130" |
| Extra Large | 46" | 134" |
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 Thermo Panel 3e 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. If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.

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.

FAQ
|
What is the thickness of the panel? The patio pacific endura flap thermo panel 3e is 1" thick. It is only thick enough for a single flap, not a double flap. |
|
Does this panel work with vinyl sliders? Yes, the endura flap 3e is compatible with most vinyl sliding patio doors for a vinyl-pet slider that matches your existing track. At 1" thick, it is thicker than most aluminum panels, so it will fit better in a vinyl track. The track width may not line up exactly with the panel, but it is only an issue with the aesthetics, not functionality. |
|
Does this keep mice, rats, and other pests out? This is a manual door, so there is no guarantee that critters will not get in. However, the Endura Flap has incredibly strong magnets that are hard for small critters to push through and get in. |
|
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. |
|
What do the Step Over Range dimensions mean? The step over is the part of the panel under the actual door opening. Depending on the flap size purchased, the stepover can range from 3"-7". This means that you can adjust it to any stepover within that range. So if you have a puppy, you can keep adjusting it as he/she grows. |
|
Will there be enough room for me to get through after the panel is installed? That depends on how wide your sliding glass door opens and how wide the panel you purchase is. Those dimensions can be found under the "Overall Panel Width" column. |
|
Can an intruder remove the Endura Flap dog door for slider from the outside? No, the thumbscrews are on the inside of the panel, so once installed, the Endura Flap Panel cannot be lifted out and removed without first loosening the thumbscrews from inside the home. |
|
What locking mechanism can I use for the Thermo Panel 3e? You'll install the included clamp lock. Alternatively, the Endura dog door/cat door for sliding glass door can be secured with a Charley Bar for added security. |
|
Does the Endura Flap dog door sliding door come with locking covers for security? Yes, these dog doors come with locking covers to ensure safety for your pet and home. Endura Flaps have locking covers that slide over them on the side facing inside your home and are made of sturdy, heavy-duty ABS plastic. Unfortunately, they cannot be used on the outside of Endura Flap Panels as an alternative. |
|
Do the Endura Flap panels require tools for installation? All panel sizes will require a flathead screwdriver for the height adjustment locks. 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. |
|
Is this door good in a cold winter climate? I want something effective in our winter months. Yes, the Endura Flap has been tested in -4°F. |
|
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. |
