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.

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.
