What is the Utah Pet Access French Door Glass Insert?

This is a full glass replacement panel for your French door that comes with a factory-installed Endura Flap pet door. Instead of cutting into your door, the existing glass is removed and replaced with a single, integrated unit.

Will this work with my French doors?

This insert is designed for Modern French doors with removable glass panels. It works with many single and double door configurations, but compatibility depends on how your glass is installed within the frame.

How do I choose the correct size?

You’ll need to measure the outside frame dimensions of your existing glass panel and match those measurements to the available insert sizes.

Product Details

Product Details

This is what a truly integrated pet door looks like. Instead of cutting into your door or adding a panel, the entire glass unit is replaced with a single, purpose-built insert that includes the pet door from the start. The result is a clean, built-in appearance that feels like it was always part of your home.

Seamless Built-In Design
The glass itself is safety-tempered and shatter-resistant, offering strength and reliability while maintaining the look and function of your original French doors. Because the frame and locking system remain untouched, you keep the security and integrity of your existing setup.

At the center of the insert is the Endura Flap, engineered to perform in demanding conditions. The material stays flexible in extreme cold and holds its shape in heat, while the magnetic seal helps the flap return into place after each use. This reduces airflow and improves overall insulation without requiring constant adjustment.

Engineered for Extreme Conditions
This configuration is especially valuable in exposed environments where wind and temperature swings can impact comfort. The sealed design, combined with optional Low-E glass, helps stabilize indoor conditions while still giving your pet the freedom to move in and out independently.

Because the insert is built as a single unit, installation is more about proper fit than assembly. Once installed, it functions as a permanent upgrade that blends into your home while delivering long-term performance.
