FAQ
What if my panel is slightly too tall?
You can trim up to 5/16" off the spring-loaded adjustment piece at the top. Remove the adjustment piece with a #2 Philips head screwdriver and use scissors to cut down the flanges. Be careful not to cut too low.
What if my panel is slightly too short?
We ofer height extensions that will add 1 1/2" to the top of the panel that you slide into the channel at the top. These are made from the same vinyl as the panel so the color will match exactly. 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 1/2", you can use small wooden shims or extra weather-stripping to fill 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.
Locking Your Door
Since you cannot lock your sliding glass door to the panel, we have provided you with a sliding door clamp lock to secure your home.
Installing the sliding door clamp:
This clamp as 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. Both block the slider from opening. When engaged, you cannot pull the sliding door away from the pet door panel.

FAQ
Is this the same as the Thermo Panel 3e?This is very similar in that it has the same height ranges, flap sizes, Endura Flap, and Low-e glass. However this one is specifically made to fit better in the wider vinyl slider tracks. |
Will this fit all vinyl doors?This will work in doors that have a recessed track at least 1 1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail |
Does it lock?We do include a c-clamp lock. It is not designed to mate with your existing sliding door lock. You can also use a Charley-Bar or dowel in the track. |
Can I install it myself?It is meant to easily be put in and removed. You just have to loosen the screws at the top, fit it into the track, and then tighten them. Then to remove it you simply loosen them again and pop it out. |
If you can remove it what prevents intruders from taking it out?The thumb screws are on the inside of the house so you can't loosen them from the outside. |
Can you lock the pet door?It comes with a closing cover, and you slide that in on the inside of the house. It is a very secure ABS plastic material that is as strong as a 1/16" sheet of steel. |
Does this insulate well?This door has superior insulating capabilities! The flap has magnets that seal all the way around, and will stay closed in wind gusts up to 50mph. The Low-e glass also compliments the insulating value of you new vinyl door. It is our #1 recommendation for extreme climates. |
What does the recommended pet height mean?That column is what we recommend be the range of pet height that would be suitable for that particular flap size. So for example if you pet is 20"tall and could fit though a 10" wide opening, then you could go with the large flap. |
How to I measure for it?You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track. |
Does it come in any color other than white?No, but the you can paint the vinyl to match. |
What if my track is wider than 1 1/2"?It can still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly. |
Does your door have to be vinyl?No, not as long as the track height and width meet the panel specs. |
What are some breeds of dogs these will fit?Small would be Chihuahuas, Yorkies, and cats. Medium would be good for Corgis, Jack Russell Terriers, and French Bulldogs. Large would fit most Labs, Goldens, and Pit Bulls. Extra Large would be good for most Rottweilers, German Shepherds on the large side, and English Labs. |
Is the flap flexible?It is flexible, but since it is two pieces sandwiched together it is a little stiffer and heavier than the more economical vinyl flaps. |
Is the flap clear?It is a little foggy, but it is see through. |
Will this form condensation like the aluminum panels?Nope! That is one of the great things about the vinyl framing is you won't have the the condensation on the inside of the house. |
How do you replace the flap?Since this is really our door mount version of the Endura Flap installed onto our vinyl panel you would replace it much like you would one installed in a regular interior/exterior door. This means that you would drill out the hole plugs to remove the screws. Then pull off the flap assembly, switch out the flaps, and reinstall the door onto the panel. All of this can be done without removing the panel from the track. |
Is there an electronic version of this panel?We do hope to offer that option in the future, but right now we are offering only the Endura Flap options. |
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. |
