Thermo Panel 2e with SureFlap Microchip Pet Door

We have paired the best patio pet panel with the best electronic pet door on the market, the Sureflap Microchip 'Pet Door'. This design is able to accommodate the largest cats and smaller dogs and employs the newest microchip sensing technology so the pet doesn’t need to wear a collar at all to use the pet door! SureFlap screws into Thermo Panel with four screws (supplied) using a Phillips screwdriver. No tools required to install Thermo Panel into sliding glass door or remove it.

Features of the Thermo Panel 2e

  • Uses the SureFlap Microchip Pet Door which has a raccoon mode that makes it very difficult for unwanted animals to enter.
  • Can be used with the vet implanted microchip or a collar key (1 collar key included).
  • Flap is 7” x 7”, making it great for even the biggest cats and small dogs.
  • The SureFlap has a 4-way locking control and a timer function that allows you to set a curfew for your pets.
  • Easy to program and is compatible with all identification microchips worldwide and SureFlap RFID collar tags.
  • The SureFlap Microchip Pet Door runs on 4 C Batteries. Typical battery life is 6 months, depending on usage, and there is a low battery indicator light.
  • This panel will not mate with an existing sliding door lock so we include either a C-Clamp Lock for adjustment ranges up to 80 1/4", or a Foot Lock for panels 80 1/4" and above. You could also use the old "broomstick in the track" method or a Charley Bar.
  • Easily install and remove your panel whenever you need; just loosen the screws at the top to release the spring-loaded mechanism and tighten back down once in place!
  • Dual-pane, low 'e' glass provides great thermal performance.
  • Heavy aluminum frame is designed to fit sliding glass door tracks at least 1” thick.
  • Built in ‘anti-whoops’ accommodates measuring errors up to ¾”. Three height ranges to fit most sliding glass doors. Don’t see your height? We can custom build one for you!
  • 90 day return policy, and a 3 year warranty for your peace of mind.

Perfect Time for a Thermo Panel 2e

  • If insulation is a concern, and you need a very raccoon resistant pet door for your sliding glass door this pet door will meet your requirements.
  • Perfect for cats that are constantly losing their collars, since it reads their embedded microchip used for identification.
  • Curfew mode allows you to only provide access during set times of the day.

Raccoon Mode

When custom mode 5 has been activated, as soon as the sensors detect an animal’s head in the tunnel of the product, it scans to read the animal’s chip. If the animal is not one whose identity is stored in the door’s memory, the two locks on the exterior of the door are activated for added security. At this point the unit will keep scanning for a microchip and the exterior locks will remain engaged until approximately 10 seconds after the intruder animal has moved away from the door. When the exterior locks are engaged it makes it impossible for the raccoon to open the door towards them in order to get in. The interior locks prevent the raccoon from pushing through the door into the house – the combination of the two sets of locks have proved impenetrable to raccoons in our product testing.
The only time that we would not recommend engaging this custom mode is if the pet tends to play with the flap by batting it away from them whilst sitting in the house. If the flap is batted far enough open into the tunnel that it triggers the sensors, the secondary locks would engage and when the flap closed the door would be locked in both directions for a period of 10 seconds or so. This makes the pet door raccoon resistant.

  • door doesn't always close & lock if wind kicks up review by Marie
    5 3 door doesn't always close & lock if wind kicks up

    If it's windy outside the pet door does not close and lock!
    This is a big problem as we live in a rural urban area and there are skunks, racoons, possums.
    Otherwise, unit operates just fine and cat had no problem learning to use it.

  • More installation required review by kev
    5 3 More installation required

    The pictures made it seem like the entire panel comes in one piece but it actually showed up in 2. We had to install the door part but it ended up being simple enough. I wish the framing was a little higher off the ground but what can you do

  • It's PERFECT review by Kenneth
    5 5 It's PERFECT

    All aspects of this product are top notch. Easy install. Looks great. Our cat was easily registered and he LOVES IT. And so do we. This is really a genius approach. Thanks so much.

  • There is hope review by Laszlo
    5 5 There is hope

    The door is in. Our young cats figured this out in a hurry. But our older cats refuse to go through the tunnel. So I used clear tape to keep the door open. So when our older cats see that there's no flap they eventually go through. Now we are on training mode. This is a nice door. The only change I recommend is that the height of the tunnel should be inch or two higher. I am looking for the day that the dual scan cat flap door will go into restricted mode. Keeping two in and the rest can come and go. Stayed tuned for on going training info updates.

  • great product for sliders review by Vickie
    5 5 great product for sliders

    My chihuahua has destroyed several sceens, plenty of door trim, and a couple of doors trying to get in when we weren't home. Costly. I found this door, and installed it a month ago. Now Suzie can go in/out whenever she wants, but no cats, possums or raccoons. We have had raccoons in garage before, through a pet door.

    It took a couple days for her to learn to come in, but now she's good. This also ended a pee on the carpet issue. It's cheaper to have the pet door.

    We got the dark color, and installed it behind fixed door. This let's us use the existing lock and sliding screen latch. It looks very good. ONE NOTE: the door panel came with light gray weatherstripping, you don't want that with your nearly back door. I replaced it with 3/4" wide by 3/8" high black foam tape, looks great, fit just fine.

    I like that if we ever wanted to, we can just remove this, no permanent holes in walls or doors.

  • Awesome! review by Chica and Fred
    5 5 Awesome!

    This door with the microchip scanner is amazing! Sure, the cats are afraid of anything new initially. But after some training with treats, they were on it. They hated the click, but sureflap had custom features which allowed me to delay the click for ten seconds. Purrfect!

    The abiity to customize locking/unlocking times is so cool. I've been living in this location for ten years, and now coyotes have come down the hill due to drought, and are too close. I'm able to prevent them from going outside after dusk, and not until after sunset.

    Whew! Lowered my stress level substantially. Now if you were to install a wifi chip, I could get text msgs from my cats saying they were locked in and safe! I wouldn't have to run home to make sure! Love technology! Thanks!

  • Awesome - total freedom for our cat review by Grant
    5 5 Awesome - total freedom for our cat

    This door is worth every penny and more:
    - Litter box is the great outdoors
    - If we travel, no worries about the cat
    - No worries about raccoons (which were a huge problem when we tried putting food outside, even on the second floor balcony!)
    - Batteries have lasted for months (do use long-lasting batteries though - we're using Duracell. The door uses almost no power, but you need batteries that can last and deliver that tiny bit of power over extended periods)
    - No more meowing and running across the pillows at night

    We trained our cat using some treats that he got if he went through the door. Had to hold it open for him and let him go through, then repeat with the door less open. Once he got used to pushing the door, he was ok. Now (a few months later), he goes out and comes in whenever he wants.

  • Great door, but drains my batteries! review by hairpuller
    5 5 Great door, but drains my batteries!

    Love the door! Cats took a couple days to really get the hang of it, but now cruise in and out all day and night! My only caveat is that my 4 C batteries only lasted a couple months.

  • Intelligent Door review by Gay
    5 5 Intelligent Door

    This door is an amazing creation. Yes, it is expensive, but it ends all your problems of unwanted neighborhood cats, raccoons, and needing to remember to lock your cat in at night. It is well made and the programing is impressive. It is worth every penny to not have to collar my cat. I feel collars are dangerous and most of the microchip doors require them. I am very grateful to Pet Doors for designing (if they did) and selling such an intelligent cat door.

  • Best door in the world review by Izzy's Dad
    5 5 Best door in the world

    We bought this door with a bit of skepticism and had all doubts laid to rest. We bought the door because Izzy's best friend is a neighbor hood stray. While we are glad he has a friend we didn't want them having any more parties when we weren't home. We replaced our standard door and the problem was solved. The door was very easy to install. It is better insulated than what we had before. Izzy was hesitent to use the door at first but after my wife shoved him through a couple of times he figured it out. I must admit the clicking of the lock freaked him out at first but now he's through the door like a shot. Using the microchip technology is pure genius. Thank you for providing the solution to our party problem.

  • Door works very well review by M
    5 5 Door works very well

    We have 6 cats and live in the NE and we needed a well insulated cat door so we don't have to either keep opening the door or keep the door partially open all the time. This door is great. It blends in very well with our sliding patio door and the insulation keeps the room from freezing. Our cats were very resistant to going through the door. One would come in but not go out. We finally added a tunnel to the inside opening. This way, they feel like they have to push to exit.

    We are still working on getting ALL the cats to use the door. But we figure if they want to bad enough, they will use it. If your animals are cooperative, the door is excellent.

    We added a charley bar and now we can lock the house and the cats can still go in and out at will.

  • Excellent With One Exception review by Mr. Bill
    5 4 Excellent With One Exception

    The sizing of the door matched our house perfectly. With simple instructions, placing this in our patio door took approximately 20 minutes. The only complaint is that the electronic lock on the dog door doesn't allow for a pet to have to wait inside for the lock to release so the pet can go outside. The description doesn't exactly make this clear.

    We ended up having to place the dog door in backwards, with the electronics outside (and exposed to the weather, unfortunately), so that our cat wouldn't escape the house without an electronic collar. We don't want her going out at all and that was the main purpose for purchasing the electronic door.

Getting Started

Installing the Sureflap Microchip Pet Door in a door

Skip to the three (3) minute mark for instructions on how to install SureFlap Pet Door into the Thermo Panel.


Thermo Panel Installation

Just ignore the Endura Flap part! The panel is the same, it just will have the Sureflap instead of the Endura Flap installed.



Installation Instructions for the Thermo Panel 2e ​with ​SureFlap Microchip Door for Sliding Glass



All Panels

1x Foam Weather Strip • 1x Center Post Weather Seal Draft Stopper

1 Piece Pet Door

1x Panel Pet Door • 1x Sliding Door Clamp

2 Piece Pet Door

1x Top Glass Panel Section • 1x Bottom Flap Section

4x Hex screws • 1x Hex wrench • 1x Threshold mount deadbolt w/screws



The aluminum, vertical panel has a patented ‘Adjustable Step-Over’ feature which permits adjusting the height of the flap to the most comfortable fit for your pet. Generally, the top of the flap should be positioned to be at least 1” (2,5 cm) above the top of the pet’s shoulder (the ‘withers’). If the factory setting is not suitable, please adjust it before proceeding. If the current setting is suitable, or you have the vinyl panel, proceed to step 3.



1A. Two-piece panels: Simply slide the pieces up and out from the bottom half of your panel to rearrange. Loosen a bottom screw if the pieces are too snug to move.

One-piece panels: Lay the entire panel on a flat surface (like the floor). Using a #2 Phillips head screwdriver, remove the bottom side-screws, and loosen the next upper screws one turn. Screws were tightly installed to hold the panel together during shipping; a drill is recommended*.

*If you do not have a Phillips head drill bit skinny enough to fit, let us know and we’ll send you one for free.

2B. One-piece panels: Once the bottom screws have been removed and the next upper side-screws loosened, the Pet Door Assembly and spacers can be removed by sliding the sections down and out of the panel. 

2C. Replace the spacers and the Pet Door Assembly by sliding them back in a different order to achieve the desired height. You can move the spacer below or above the flap to raise or lower the flap height.

The order of the pieces is important! The piece on the bottom needs to always be at the bottom, as that is where the screws attach. 

When finished, replace the bottom side-screws and tighten the next upper-side screws for one piece panels and skip to step 4. For two-piece panels, you can now assemble the patio panel!

Note on flap height and pet size:

A lower step-over height is easier for pets to navigate. However, if the top of the flap is low enough that the pet needs to crouch to get through their pet door, they can injure themselves and possibly cause the pet door to malfunction. If your pet door does not sit at a comfortable height for your pet, you may need a larger size flap. 


(if you have a single piece panel, please proceed to step 4)


3A. Align the aluminum connectors extending from the bottom flap panel section with the top glass panel section. Press the aluminum connectors into the holes at the bottom of the top glass panel section. Ensure locking cover & thumb screws are on the same side!

3B. Gently tap the bottom surface of the panel against the ground to completely insert the connectors. Protect hard surfaces to prevent scratching. The components of the panel are designed to slide together very tightly.

3C. Fasten the two panels together using the four stainless steel hex head screws found in the panel packaging. Use the hex wrench to tighten screws so the two halves of the door are pulled together. 

Note: Screw holes may look misaligned; this is intentional to ensure a tight fit. The panels will squeeze together as the screws are tightened.

4. Loosen the thumb screws at the top of the pet panel. This allows the spring mechanism to move freely up and down.

5. To insert the panel pet door into the top track, push up against the spring mechanism and swing the bottom of the panel up and over the threshold. Seat the panel on top of the small guide rail in the track. If you can’t quite get it in the track, try swinging in from the outside as the outside track wall may be shorter.

You want to put the pet door in your track before applying any weather-stripping to ensure it fits! If it fits well, move on to the next step. See our tips at the end of these steps if you have trouble!

6. Once you’re sure the panel fits, remove the panel from the frame and lay it on its side on the ground. Apply the foam weather-stripping 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, trim to fit with scissors. 

7. The center post weather seal strip (draft stopper) should be installed on the inside of the home. It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel. This strip prevents air leaking between the sliding glass door and the stationary panel. Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.



Since you cannot lock your sliding glass door to your panel pet door, we have provided you with an alternative locking method to secure your home:

Doors over 80 1⁄4” (203,8 cm) Tall

Installing the threshold mount deadbolt lock: For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the back of the slider using the mounting screws provided. For doors manufactured with the slider on the outside, the lock is installed on the leading edge of the stationary panel.

Drill a 3⁄16” (4,8 mm) hole into the frame opposite the steel deadbolt lock. This hole MUST be 3⁄4” (1,9 cm) away

from the inside edge of the door’s frame to avoid drilling into the glass. Drilling into the glass will cause the glass to shatter.

Doors under 80 1⁄4” (203,8 cm) tall

Installing the sliding door clamp: This clamp has a screw which 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.






1x Panel

1x Foam Weather Strip

1x Center Post Weather Seal Draft Stopper

Separate Box:

1x Microchip pet/cat door



You will need to do a couple extra steps to install your SureFlap Microchip Pet Door, Cat Flap or DualScan through your panel. The SureFlap ships in a separate box, and before you open it you should first test to make sure your panel will work in your door or window. Follow steps 1 & 2 from the Panel Installation Instructions.

Remove your SureFlap from its box, and follow the directions included to program the pet door. You can then proceed with the instructions below!




Insert SureFlap Cat Flap into hole

1.  After testing the panel to make sure it works in your window or door, and testing that the SureFlap will work with your pets, you are ready to attach the pet door to the hole in the panel!

Screw SureFlap Cat Door in place

2. Find the middle length screws in the SureFlap box. The Pet Door version uses 4 screws, while the Cat Flap and Dual Scan will only utilize 2 screws.

Thumbscrews should be on the same side as the controls of your SureFlap. Installing your SureFlap with the controls on the outside of your home will damage the pet door and void SureFlap’s warranty.

3. The trim frame and screws will go on the ouside of the panel. Place the side with the locking controls on the inside of the panel. The controls will need to be on the same side as the thumbscrews. You can then follow the remaining instructions for either the vertical or horizontal panels.



You might choose to secure your pet door 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.  



Some stationary 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 if 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.
