In terms of storage options, both LFC22740 and LFC20740 come equipped with adjustable shelving. This flexibility allows users to customize their storage space according to their needs, whether it’s for large party platters or day-to-day items. Additionally, the refrigerator compartments include humidity-controlled crispers, which are ideal for storing fruits and vegetables, ensuring they stay fresh and crisp longer.

For added convenience, both models feature an external ice and water dispenser. This not only provides instant access to chilled water and ice but also adds a touch of sophistication to the overall design. The sleek finish of these models, available in stainless steel, makes them an attractive addition to any kitchen décor.
