Please read instructions & notes thoroughly before installation. If you need to adjust the step-over height, complete steps A-C before installing the panel in your track.
The following steps apply if you need to adjust the step-over height. If you need to adjust the step-over, complete these steps before installing the panel in your track.
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.
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.
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.
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.
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.
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.
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.
Is this the same as the Thermo Panel 3e? No, this panel has vinyl framing whereas the Thermo Panel 3e has aluminum framing. Read about the differences between vinyl and aluminum pet door panels here. |
Will it fit all vinyl sliding glass doors? This panel fits 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 to lock the panel in place in your slider track. However, the panel does not mate with your existing sliding door lock. You can also use a Charley bar or wooden dowel for additional security. |
Can an intruder remove it from the outside? The thumbscrews are on the inside of the house so you cannot loosen them from the outside. |
Does the flap lock? The severe weather vinyl sliding door panel comes with a secure locking cover to block access to the flap when needed. |
Does this panel insulate well? Yes, it insulates very well. The flap is lined with magnets on three sides to stay shut in winds up to 50mph. The glass in the panel is Low-E for maximum insulation. |
How do 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 for your track height. |
Does it come in any color other than white? No, but the vinyl can be painted to match your home. |
What if my track is wider than 1-1/2"? It will 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, this can work for aluminum sliders with tracks at least 1.5" thick. |
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 so it's easy for pets to use. |
Will this form condensation like the aluminum panels? Nope! One of the benefits of a vinyl panel is that it won't "sweat" in cold weather the way aluminum panels can. |
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.
