Product Details

The Custom Endura Flap Cat Door for Horizontal Sliding Windows offers a practical solution for your pets to enter and exit as they please. This custom-fit cat door is specifically designed to fit seamlessly into your horizontal sliding window track, ensuring a secure and snug installation without any permanent alterations—making it perfect for renters.

Constructed with a durable aluminum or vinyl frame and featuring safety glass, this cat door provides improved energy efficiency while allowing sunlight inside. For smaller height ranges, the panel may be all metal instead of glass. The flap is lined with adjustable magnets to resist heavy winds and extreme temperatures, remaining flexible even in -40°F conditions and staying sealed in winds up to 50mph.

Installation is a breeze with the spring-loaded design, and the removable panel comes with a C-clamp lock, draft stopper, and weather stripping for added security and insulation. The cat door is available in three stylish finishes: white and bronze, allowing you to match your window frame effortlessly.

The panels have a 3" spring-loaded height adjustment, so if you have a 48" track, for example, the panel you choose will adjust from 46" – 49" inches. 

Not only will this cat door provide your pets with newfound freedom, but it will also enhance your home's overall aesthetic. 


Features:

  • Aluminum or vinyl frame designed to fit into a window track width of at least 1" thick
  • Spring-loaded design ensures secure and easy installation
  • Adjustable magnets for heavy wind and temperature resistance
  • Removable panel with built-in cat door for flexibility and convenience
  • Sturdy locking cover keeps pets inside when needed
  • Available in white and bronze to match your window frame

Do not know which size to get? Here is a measurement guide to help you out.

Aluminum panel has 1" framing, measure your track width to make sure that your window will accommodate the panel.

If your measured track height does not fall within one of the ranges above, we can make a custom height. Custom height option may take up to 4 weeks to special order the glass and build the panel. If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.

Very well designed. Excellent quality. Very easy to install - as advertised. No actual installation instructions were included, only a QR code which lead to an installation video for a sliding glass door ( I had a window insert). I would have been nice to have more details.

Custom order. Fits great

Order a custom size and it fits and works great. One cat can’t get enough and the other still thinks his brother is teleporting to the other side of the window.

Excellent Choice for Windows (Staff Review)

This panel is an excellent choice for installing a cat door in your window. Highly insulating flap and comes with weatherstripping to prevent any drafts.

Cat door

It was easy to put in, but so far the cats haven’t used it. They have not been out in this freezing weather, so it probably won’t be until spring that we will know how well it will work for us.

Best cat door ever!

I purchased this cat door just in time - before the cold Fall/Winter weather! It works great - very well constructed. It keeps out the cold temps and NE wind. It fits perfect in .horizontal window. The cat had to get used to a smaller opening; but he adjusted just fine. PetDoors delivered ahead of schedule! Thank you!
