Parts
- 1 Vinyl Panel Pet Door
- 1 Weatherstrip Seal Roll
- 1 Center Post Weather Seal Draft Stopper
Tools
- #2 Philips head screw driver
- Non-metal hammer
- Scissors
Please read instructions & notes thoroughly before installation.
Step 1 Separate Flap Frames
- Lay the entire panel on a flat surface. Use a #2 Philips head screwdriver to unscrew the four frame screws from the flap frames to separate them, then set them aside.
Step 2 Loosen Side-Screws
- Loosen both the middle and bottom sets of side-screws by one turn.
Step 3 Adjust Stepover Height
- Once the bottom and middle side-screws are loosened, slide the spacer(s) down to the bottom of the panel. Pull the adjustable seal extrusion(s) down and out to place it between the adjustable spacer and the adjacent crosspiece.
- You can move the spacer(s) above or below the flap to raise or lower it until the desired flap height is achieved.
Step 4 Replace Side and Middle Screws
- Once the desired flap height is achieved, replace and tighten the bottom side-screws and tighten the middle side-screws.
Step 5 Reattach Flap Frames
- To reinstate the pet door assembly, sandwich the interior and exterior frames on either side of the pane how they came. Insert the four frame screws through the pet door frames.
Step 6 Add Hole Plugs
- Use the wooden of a hammer, a rubber mallet, or another non-metal tool to tap the hole plugs over the eight exposed frame screws.
Step 7 Loosen Height Adjustment Locks
- Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.
Step 8 Insert Panel Into Track
- Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
Step 9 Apply Weatherstrip
- Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
- Apply the foam weatherstrip seal by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides and trim to fit with scissors.
Step 10 Place Panel In Track
- Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.
Step 11 Install the Draft Stopper
- The center post weather seal strip (draft stopper) should be installed on the inside of the home.
- Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
- Repeat step two to install the panel in your track.
How to Adjust Stepover Height
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, and Low-e glass. However, this vinyl panel is specifically made to fit better in the wider vinyl slider tracks. 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. |

This doggie door is God sent miracle!
No longer have to get up in the middle of the night to let my dogs out or in the morning before I go to work. It may take a little while for your dogs to get the hang of using it, but eventually they will. Some reviews said the foam around the edges is less than adequate. I didn’t have the same opinion. It seemed plenty thick enough for shipping the door. Oh remember to unscrew the chrome knobs a little to release the extension part. I forgot about that lol.

United StatesShould of just bought a cheaper door
The quality of this door is terrible. For supporting an American made product I feel like I could have got the same quality from a Chinese made door. The screw holes in the extender piece below the door were in terrible shape when I received the door. It looked like a company with no quality control made the door. My sliding door measured 78.5” and the door didn’t even fit easily. I had to take the top adjustment piece off and jam foam weather seal tap into the top of the door. Also the foam weather seal they send you is junk! I ended up having to make another trip to Home Depot to buy $50 worth of quality rubber weather seal tape to finish the job correctly. You’d think for a “severe weather” friendly door they’d give you the best weather seal tape that also should have been white to match the white vinyl. Who ever made this door cut corners and gave me cheap material. I also should caulk around the extender bottoms piece below the door since I can see sunlight coming through it. Seriously disappointed in purchasing a premium American made dog door. Makes me sad how poorly made it was.

United StatesThis is amazing
This is great. I almost didnt buy one after reading the other reviews but I'm glad I did. I dont know why some people have given this negative reviews other than not understanding how to install it properly. Some background - I live in the midwest where windy conditions are common. 30 mph with 50 mph gusts so days. My house faces north/south with my sliding door facing south. In the summer, this means that south wind is blowing against my door all the time. I had been through 3 big box store brand sliding glass door pet doors. None of them could handle the wind and they all started wearing out after 18-24 months. They never sealed very well which meant they let in cold air in the winter and hot air in the summer (as well as bugs in the summer). My endura flap extreme door has been worth every penny. Two days after I installed my door it was very windy and the flaps didn't budge - no air leakage at all. Yes, it was an investment to make but worth it for me.

United StatesNot up to hope & expectation
Door does not close reliably. Old, much cheaper single flap door was better. The foam “seals” where the slider meets the fixed dog-door panel is a cheap and completely, self-defeatingly cheap, ****** solution. Had to tape around the top, bottom, and other side of there panel to prevent wicked draft and heat loss; the foam side is unremediable since it has to move and leaks cold very badly. Plus that cheap foam and standard double-stick tape will break down quickly. Tape is already coming unstuck, foam crumbling. Around “storm flap” of course, leaks heat and allows cold air in at least as badly as cheap, old door that this was Intended to replace. If this was inexpensive, it would still be a disappointment and failure, however, it was VERY expensive to boot, I would never recommend this item. Sales rep on phone was very nice and helpful, and called before shipping to let me know I had ordered an unnecessary and expensive additional part, which she removed from the order and refunded. At least.

United StatesNot so good
Customer service was nice but the door itself, not so much. The plastic pieces that hold the magnets on the bottom of the faps were too large and wouldn't allow the flaps on the door to open. I even had difficulty pushing it through. Also once pushed through it would allow the flap to come back and center up. The panel also fit slightly crooked. For the money I paid I expected a higher quality item. I've had nothing but issues with it. Going to call customer service again and see what they can do.
