- Simple design allows you to easily install and remove your panel as necessary; simply loosen the thumbscrews at the top to release the spring-loaded mechanism and tighten once in place!
- Choose from four different sizes that have a high aspect ratio, meaning they are taller and narrower to better fit more pets.

Perfect Time for a Thermo Panel 3e
- If insulation is a concern, the Thermo Panel 3e is the most insulated pet door available for sliding glass doors. Perfect for extreme weather conditions, whether it be sun, snow, wind or rain.
- You find yourself replacing flaps constantly, as the Endura Flap often only needs replacing if a dog decides to take a bite out of it! It rotates on a rod at the top to eliminate any stress points that might tear over time.
- If you have multiple dogs sharing a pet door, the taller design of the Endura Flap can help you accommodate the height of the larger dog while keeping the flap low enough for the shorter dog to step through.
Most sliding glass doors will accommodate the three panel sizes we offer. But if our standard panels do not match your door size, we can build a custom Thermal Panel 3e for you. We can also custom make a panel for a miniature sliding glass door, provided the window track width is at least one inch.
The panels have a 3-inch spring-loaded height adjustment, so if you request a 40-inch panel, the panel you receive will adjust from 38 to 41 inches.
