The Endura Flap Thermo Panel 3e is engineered for pet owners seeking a premium sliding glass pet door without permanent home construction. Designed as a vertical insert, it installs directly into your existing track to give your pet effortless access while keeping your original door intact.

Streamlined Track Compatibility
Built for aluminum sliding patio doors with a track width of at least 1", this model offers exceptional versatility, including dedicated adapters for seamless integration with monorail track systems.

Extreme Climate Protection
At the heart of the panel is the Endura Flap, crafted from a flexible polyolefin polymer that remains pliable in temperatures down to -40°F without warping in extreme heat. Its three-sided magnetic seal snaps shut reliably after each pass, blocking drafts and holding firm against wind gusts up to 50 mph.

The upper section features single-pane safety glass for added strength, insulation, and a clean, modern profile that stands up to daily use by pets of all sizes.

Dual-Layer Home Security
To maintain complete safety and control, the panel comes equipped with a rigid interior locking cover for the pet opening alongside a heavy-duty Endura Flap Slide Lock to keep your sliding glass door securely locked from the inside.
