The door swing on a Sub-Zero IC-30 refrigerator is designed to open to a 130-degree angle. This allows for easy access to the interior compartments, making it convenient to load and unload items. The 130-degree door swing ensures that the refrigerator door does not obstruct the adjacent cabinetry or other appliances, allowing for a more efficient use of space in the kitchen. Additionally, the door swing can be reversed during installation to accommodate different kitchen layouts and user preferences. This flexibility in door swing direction makes the Sub-Zero IC-30 refrigerator a versatile choice for various kitchen configurations.
