— the door-on-door mounting is a method of attaching a built-in refrigerator, where the decorative facade is directly attached to the refrigerator door through hinges. This type of mounting allows the door to open wider, up to 110-115˚ or more, and creates a seamless appearance between the facade and the refrigerator. However, this method may add extra weight on the door hinges, leading to potential sagging issues if not properly designed.
