The Endura Flap E2 Pet Door for Walls is a well-designed option for pet owners looking for an energy-efficient and weather-resistant dog door. The large size, with a flap measuring 10” x 18”, is suitable for pets up to 27” tall, making it ideal for medium to large dogs. The double-flap design provides excellent insulation, reducing energy costs and maintaining indoor comfort even in harsh weather conditions, as it can withstand winds up to 50mph and temperatures down to -40 degrees F. The aluminum frame ensures durability, and the white finish allows it to blend seamlessly with most home exteriors.

Installation is straightforward with step-by-step instructions, although it requires wall thickness between 2” to 8”, which might be a limitation for some homes. The magnetic closure system is adjustable, helping with easy training for pets while offering the necessary security to keep out wind and drafts. On the downside, the door weighs 22.9 pounds, which could make installation more challenging, and it might be considered expensive compared to simpler models.
