With a built-in refrigerator with a door-to-door hinge system, the door of the refrigerator is secured to the front panel. The advantage of this is that the refrigerator door connects well to the panel. Moreover, the door also opens further. Do you now have a towing door system? No problem, it is possible to switch to a built-in refrigerator with door to door. Remember that you must remove the hinges and door guides from the front panel.
