Showcase the unparalleled durability and energy efficiency of the Heavy Duty Dog Door by Gun Dog House Door Company. Designed specifically for medium and large dogs, this door is guaranteed to withstand the rigors of all types of kennels - professional gun dog kennels, boarding kennels, or amateur kennels. The robust construction features a die-cast aluminum frame, 1/4" clear Plexiglas, and heavy-duty hinges, making it the best dog door on the market for metal buildings, walls, and dog houses.

This door stands out among the competition as the only two-way dog door with 'special' heavy-duty spring-loaded hinges that provide a positive weather seal. Upon your dog's exit, the entire assembly opens up about the mounting bar's hinges. When the dog returns, only the acrylic panel tactfully passes through the wall/door, using the hinges attached to the panel, allowing your dog back inside, and keeping the cold air out in winter and the insects out in summer.

The Heavy Duty Dog Door is not only energy efficient, but it is also chew-proof, ensuring long-lasting durability. It also provides an easy-to-install solution, making it the best choice for your kennel door or gun dog door.

Choose the Heavy Duty Dog Door by Gun Dog House Door Company, for a secure, comfortable, and energy-efficient solution for your dog's entry and exit needs.
