Energy-Efficient Safety Glass
Outfitted with durable single-pane safety glass, the panel maintains natural light and outdoor visibility while insulating your home against seasonal weather and temperature changes.

All-Weather Magnetic Flap
The clear vinyl pet flap uses magnetic closure strips and weatherstripping to prevent wind and draft infiltration.
