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.

Well made. Sturdy. Movement on flap is louder (clicking). Wish the step over could be adjusted lower.

Good albeit expensive solution

I like the product, and it suits our needs pretty well. The package didn't come with enough weather stripping to span the space needed, and I can't imagine it's something we will be able to leave in year round (because of air getting in), but it is a well built item that gets the job done without needing to knockout walls, or cut into doors which is nice. If it was less expensive I'd be singing its praises, but for the price it's adequate. Thanks

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.
