LG maintained the design identity of the French Door model for the product and partially varied its modular components, so that it can be applied to various models from the InstaView model to the Wine model. While the rail of the wine cellar shelf is fixed at the inside of the refrigerator in general, the shelf of the LG SIGNATURE Wine model combined the cantilever and the under-rail so that the user can change the layout of the wine shelf. The shelf part that the wine bottle contacts directly is made of wood, and aluminum is used at the front of the shelf to provide a sense of unity with the interior.
