This panel is designed for homeowners who want better insulation and pet access without changing their existing sliding door. Once installed, it works alongside the door to create a dedicated entry point while maintaining a clean, integrated look.

Insulation That Goes Beyond
The dual-pane Low-E glass helps reduce heat transfer and limit solar gain, creating a more stable indoor environment compared to standard single-pane inserts. Paired with the Endura Flap, the panel supports a more controlled barrier between inside and out.

The Endura Flap remains flexible in extreme cold while maintaining its shape in heat. Magnets along three sides help the flap return to a closed position after each use, supporting a consistent seal that resists wind pressure and helps prevent unwanted airflow.

A Secure, Drill-Free Fit
The aluminum frame is designed to fit securely within most sliding door tracks while maintaining a slim profile. Adjustable height locks compress the panel into place, creating a stable installation without the need to drill into the door frame.

When the sliding door’s original latch can no longer engage, the included Slide Lock provides a dedicated solution. Mounted to the frame, it creates a secure stop point that helps prevent the door from being opened from the outside.

Panels are available in multiple standard height ranges and can be custom built for uncommon track sizes. Larger configurations ship in sections for easier handling and assemble with included hardware before installation.

Designed for Everyday Use
With controlled pet access, durable materials, and thoughtful integration into your existing door, this panel offers a balanced solution for convenience, comfort, and security in daily life.
