This panel is engineered for homeowners who want maximum energy efficiency and home security without replacing their existing sliding glass door. Featuring dual-pane Low-E safety glass and a magnetic-sealed Endura Flap, it limits drafts and blocks solar heat gain to keep your living space comfortable year-round.

High-Performance Weather Insulation
The Endura Flap remains flexible in subzero cold and holds its shape in extreme heat. Its three-sided magnetic seal forms a tight closure that holds firm against heavy wind gusts up to 50 mph.

Tool-Free Tension Fit
The 1" aluminum frame offers a sturdy, streamlined profile that fits securely into standard sliding door tracks. Built-in adjustable height locks compress the panel into place for a rock-solid setup without drilling into your frame.

Panels adjust across multiple standard height ranges or can be custom-built to match unique measurements. Taller or wider configurations ship in two sections for convenient transport and assemble easily with included hardware.

Dedicated Sliding Door Security
Because panel inserts prevent native door latches from engaging, this model includes a steel Endura Flap Slide Lock. It mounts directly to the frame to create a physical stop point, ensuring the sliding door cannot be forced open from the outside.
