The Thermo Panel 2e with the SureFlap Microchip Cat Door is an energy-efficient sliding glass electronic pet door that utilizes microchip-sensing technology to prohibit pesky animals from accessing your home. With a spring-loaded design, this cat flap door panel fits into a wide variety of track heights. As one of the best microchip cat flaps on the market, this patio panel pet door senses your cat's microchip when they come back inside, preventing any animal without a programmed chip from entering. The panel and pet door ship separately. You will have to attach the pet door to the panel using screws (which are provided).

    Caution: Prior to installation, it is the responsibility of the user to consult all building codes which may influence the fitting of the cat flap and assess the suitability of a given installation. The user must also consider potential hazards present inside or outside the cat flap as well as the impact that subsequent modifications to your property may have on the existence and use of your cat flap. It is recommended that these assessments are conducted in consultation with a construction professional.

    Do not install SureFlap™ in a fire door as it will render the fire door unfit for purpose.

    Installation Instructions

    Please Note: 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 4.


    ADJUSTING THE STEPOVER HEIGHT - OPTIONAL (for aluminum panels only)

    Step 1:

    • 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.


    Please Note: 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.

    Step 2:

    • 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.

    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.

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

    Step 3:

    • One-piece panels: Replace the bottom side-screws and tighten the next upper-side screws for one piece panels and skip to step 7.
    • Two-piece panels: You can now assemble the patio panel.


    Please Note: In regard to 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.

    TWO-PIECE PANEL (Steps 4-6)

    (If you have a single-piece panel, please proceed to step 7)

    Step 4: 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!

    Step 5: 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.

    Step 6: 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.

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

    Step 7: Loosen the thumb screws at the top of the pet panel. This allows the spring mechanism to move freely up and down.

    Step 8: 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.

    Please Note: 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.

    Step 9: 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.

    Step 10: 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:

    • 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.



    Parts & Tools

    • Panel
    • Foam weather stripping
    • Center post weather seal draft stopper
    • Microchip cat door


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

    Step 2: Find the 2 middle length screws in the SureFlap box.

    Please Note: 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.

    Step 3: The trim frame and screws will go on the outside 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 can 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.

    Stationary Panel:

    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.



    Getting Started: Some pets will take longer than others to acclimate to their new door, so patience is key! Never push or shove your pet through the door (this will only develop negative feelings). Instead, follow these training tips + tricks to help introduce your pet to the door gradually.

    Limit training sessions to no more than 10 minutes at a time. Two well spaced out sessions per day should be the maximum.

    Hold the flap all the way open for your pet at first, then a little less each subsequent time so your pet learns to push through on their own. Stay consistent with verbal encouragement and treats for best results.


    Teaching Your Cat to Use Their Door:

    Step One: Introduce your cat to the door by putting your hand through it so they know how it works. Have them inspect the new cat flap to get used to the look and smell (this is a great time to program your cat’s microchip!).  

    Tip: You can wipe your cat’s face or body with a cloth and wipe the door with the same cloth to give it a more familiar scent. 

    Step Two: Some cat doors make a slight clicking noise when opening and closing which can scare timid cats. Try manually opening and shutting the flap slowly to familiarize your cat with this noise. 

    Step Three: Get your kitty’s favorite treats or toy ready! Start by using a treat to encourage your cat through while holding the flap open for them. Once they are comfortable, start lowering the flap on them as they walk through for their treat.

    Tip: Be sure to train your cat using the actual door height - meaning raise the door enough so it resembles how high it will be once installed.

    Tip: If you have a door with non-removable magnets, putting some painter’s tape over the magnets can help decrease the magnet attraction strength temporarily for training purposes.

    Step Four: Always make sure to reward your cat with praise (and maybe another treat) when they pass through the door.  Remember: training can take a considerable amount of time. There is no standard practice as every cat is unique.


    Quick Tips:

    1. 1. For especially timid cats, temporarily tape it up out of the way while they get used to the idea of walking through the tunnel.
    2. 2. Clear flaps may confuse pets as they might think the flap is a window. Try putting a piece of masking tape on the clear flap to distinguish it from a window and reinforce to your pet its use as a door.
    3. 3. Magnetic and weighted flaps have additional weight which may be difficult for your pet to push through. Fix this problem by gently pushing the door to assist your pet as they go through or removing the magnet until your pet gets used to the full weight of the door on their own.
    4. 4. If you plan on installing more than one pet door, use the same flap if possible for consistency.
    5. 5. Electronic flaps make a small clicking noise when the flap is activated that may frighten timid pets. The best way to remedy this problem is to positively reinforce this sound in your pet’s mind.
    6. 6. Praise your pet when they come near the door and hear the activation noise.
    7. 7. If this does not work, disable the electronics with “training mode” and have your pet use the door manually for a week or so while getting acquainted with the door.
    8. 8. Consistency is key! Stay consistent both in your training methods and your choice of pet doors. If you have multiple pets the first to learn will often demonstrate  for the others!
    9. 9. When your first lock the flap shut, introduce your pet slowly rather than letting them “learn the hard way” by running into it.


    Will this make a good electronic dog door?

    While some dog owners report that their small dogs can fit through the largest Sureflap pet door flap size, most dogs will have trouble fitting through. If you have a large dog and want an electronic dog door, we recommend checking out the High Tech Pet Power Pet Door, which uses collar tags and comes in sizes big enough for extra large dogs. Another option is the Petsafe Electronic Smartdoor, which can sense a smart key attached to your dog's collar; a great option for installation in doors or walls.

    Is there a version of this door that I can install into my wall? What about my sash window?

    You can find the Sureflap Microchip Cat door here, but for in-wall installations, you might need to purchase a tunnel extender so that you have a stable wall entry doggie door. For sash windows, you can check out the Thermo Sash 2e with Dualscan Cat Flap, which will give your cat easy access outside without inviting in raccoons.
