  • 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.

How to Install Your Thermo Sash with Dualscan SureFlap Cat Door 

Insert SureFlap Cat Flap into hole

  • You will find the SureFlap Dualscan Cat Door in a separate box from your Thermo Sash. There will be a hole in the sash for the SureFlap to be installed. Note the inside of the Thermo Sash will be the side with the thumbscrews.
  • Mount the cat door in the hole with the main assembly that has the battery covers and LCD screen facing inside the house, on the same side that the thumbscrews of the Thermo Sash are mounted.
  • Mount the external frame on the outside of the Thermo Sash, the side without thumbscrews, and screw the external frame to the main SureFlap assembly.
  • Screw SureFlap Cat Door in placeYou can now install the entire unit into your window. Release the thumbscrews so that the spring-loaded side can extend and compress.
  • Place the spring-loaded end in one side of your window track with thumbscrews facing the inside of the home. Compress the pet door towards the spring-loaded side and insert the other side into the opposite side of the window track.
  • You can then tighten the thumbscrews to secure the cat door and close the window!
  • Once you make sure everything fits, you can add the foam weatherstripping to the Thermo Sash and place the screw caps over the screw holes on the external frame of the SureFlap. Align the screw caps with the slot pointing outwards and push firmly into place. (To remove the screw caps slide a flat blade screwdriver into the side slot and pry the cap out of the hole.)

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