PETCOMING 3-Flaps Aluminum XL Dog Door for Wall

• 3-Flaps Extreme Weather Protection: Upgraded from traditional 2-flap designs, this insulated dog door features an added thermal insulation layer and advanced insulation materials for improved temperature control and energy efficiency. The triple-flap system helps block cold drafts, heat, wind, and outdoor air for a more comfortable indoor environment year-round.
• Heavy-Duty Aluminum Construction:Crafted entirely from premium aluminum alloy and reinforced with an upgraded welding process, this dog door is built for superior strength, durability, and long-term performance. Unlike common plastic, iron, or low-grade alloy pet doors, the solid aluminum frame is lightweight yet highly resistant to bending, warping, rust, and paint peeling, making it ideal for large active pets and everyday use in all weather conditions.
• Generous Size for Giant Pets: Flap opening 23.7 x 16.2 inches. Designed for dogs up to 220 LB, this heavy-duty dog door gives extra-large breeds the freedom to go outside safely and comfortably. Perfect for Great Danes, Newfoundlands, Irish Wolfhounds, Saint Bernards, and other giant dogs who need frequent outdoor access.
• Secure & Safe When Needed: Features dual security locks and a removable closing panel to help keep unwanted animals out and your home secure at night, during travel, or in bad weather. A practical solution for pet owners who want both convenience and security. Bonus: 2 firefighter stickers alert rescuers in case of emergencies, ensuring your furry friends are safe.
