  • Awesome Raccoon proof door review by ceek
    5 5 Awesome Raccoon proof door

    This door is a life saver. Raccoons were getting in the house via the door and this door will not let them in. The cat has the chip and the door only unlocks for the cat to exit and only unlocks for the cat to enter. The raccoons cannot pry open the door from the outside to come in which is great. The quality of the frame is great. It is a heavy duty aluminum frame and you can tell it is wel built. The glass is dual pane so I do not feel the cold air coming through. Overall this door is amazing.

  • Very well built but pricey review by Harold
    5 4 Very well built but pricey

    Its a great door and seems like a very well built frame. You will definitely want to recheck your measurements because it only has a 3 inch adjustment range it looks like. The pet door comes in a separate box and needs to be installed (pretty simple installation). Works great for keeping out other critters and allowing free range for my cats. I just wish it wasn't so pricey

  • Fits an issue review by Zoie
    5 3 Fits an issue

    Frame was too thick for the window so it wouldn't fit inside properly. Have to use a piece of wood in the end that was thinner, put that in the little channel and it fit into the track. On the other end there is no channel so that got drilled in and held with screws.

  • Does everything I need! review by Cath
    5 5 Does everything I need!

    I have 2 cats, one outside/inside and one just inside. This is perfect for letting my outside cat outside while keeping my other cat inside. It feels like a very high-quality product. The pet door does not come installed on the panel so some assembly is required. The opening is a bit small and I don't think my chubby inside cat would be able to use this even if he wanted to.

  • Great Option for Multiple Cat Households review by Mars
    5 5 Great Option for Multiple Cat Households

    This is a really great option for homes that have indoor/outdoor cats and indoor only cats since the door can be programmed to let out only certain cats using their microchip. I also like that it keeps out unwanted guests including raccoons. Make sure you measure the width of your window correctly for a good fit. Very high quality build.

Installation Instructions for the Thermo Sash 2e with DualScan Cat Flap


1x Window pet door

1x Foam Weather Strip

1x Center Post Weather Seal Draft Stopper



1Loosen the thumb screws at the end of the sash. This allows the spring mechanism to move freely side to side.

2. Insert the sash into the window track. Push against the spring mechanism and swing the opposite end into the opposite window track. Gently release. Tighten the thumbscrews.

If the pet door sits properly, remove the pet door to put on the foam weather-stripping in step 3.

3. 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 the top and the bottom. Trim to fit with scissors.

4. Mount the draft stopper vinyl weather strip. This strip prevents air leaking between the window frame when raised to accommodate the sash. Trim to fit with scissors.



For a permanent lock, install a wood screw in the track immediately above the window on both sides. You will no longer be able to raise the window.

For a temporary lock, place a removable wooden dowel or charley bar in either track above the window.



Remove the screws on the top and bottom closest to the edge of the pet door. Then slightly loosen the screws closest to the glass. Next, slide off the side piece, then the flap assembly. Rotate the flap assembly (essentially flipping it upside down) then slide it back in. Make sure the locking cover is on the same side as the thumb screws.Replace the end spacer and screws.



Make sure you place steps or ramps leading to your pet’s door at a height that works! When they go through the flap, the top of the flap should be at least 1” (2,5 cm) higher than the top of their back. Watch your pet and adjust as needed to keep them comfortable.





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.

Q: What 3 things do I have to know/measure when choosing a pet door for sash window?
