The Endura Flap® Cat Door for Horizontal Sliding Windows is made to fit into the existing track of your side-to-side sliding window. This removable panel does not require tools or any complex installation, as the spring-loaded design safely secures the panel in place without making any permanent alterations (perfect for renters!). It features dual-pane, Low-E glass that is UV and infrared resistant and insulating. The flexible vinyl flap is lined with adjustable magnets to resist heavy wind and extreme temperatures.

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