Door & Wall Mounted Versions
Note: While the SmartPet Aluminum Pet Doors are suitable for use in a residential application, they are more commonly used in commercial kennel facilities. The flap on this pet door is relatively heavy and may not be suitable for pets that tend to shy away from doors that feel weighted on their backs. Small dogs and cats may have a hard time pushing through the door.
