Product Details
This insert is built specifically for vertical sliding windows, allowing you to add a pet door without cutting into walls or doors. It sits cleanly within the window track, preserving the look and function of your home.
Quick Setup No Commitment
The spring-loaded design holds the panel in place using pressure within the track, so installation is fast and removal is just as easy. This makes it especially useful for renters or anyone who wants flexibility without permanent changes.
Comfort Through Every Season
The insulating glass panel helps reduce energy loss, while the magnetic-sealing flap returns into place after each use. Together, these elements help limit drafts and maintain a more stable indoor environment.
The aluminum frame provides structure and durability, while the flap is designed to remain flexible across a wide range of temperatures. This ensures consistent performance even with frequent use.
Flexible for Your Setup
The adjustable width allows the panel to fit a variety of window sizes, and the flap orientation can be configured to suit your space. For elevated windows, adding a step or ramp can make access easier for your cat.
