Designed for long-lasting performance and superior weather protection, the Endura Flap Pet Door for Exterior Walls offers a secure and energy-efficient way to give your pet the freedom to come and go. Built to install into standard walls 4½" to 8" thick, this wall-mounted pet door features a heavy-duty aluminum frame available in white or black, paired with a telescoping tunnel for a clean, weatherproof fit. Whether you have a small cat or a giant breed dog, multiple flap sizes are available to provide the right fit for your pet.
Choose between a single flap model for moderate climates or a double flap version for enhanced insulation in extreme conditions. Each flap is crafted from a patented polyolefin polymer that stays flexible in subzero temperatures as low as -40°F and seals tightly with magnets on three sides to block wind gusts up to 50 mph. The tall, narrow flap shape is designed to reduce the opening size while still accommodating pets of varying heights, helping to preserve indoor climate control.
The included locking cover—made from impact-resistant ABS plastic and engineered to match the strength of a 16-gauge steel plate—slides into the interior frame to block access when needed. Whether installed in a kitchen wall, garage, or utility room, this pet door delivers industrial-grade reliability in a streamlined design. Proudly designed, engineered, and backed by a lifetime warranty, the Endura Flap Pet Door for Walls is a smart investment in your pet’s independence and your home’s energy efficiency.
