This is a supportive and decorative structure mounted beneath shelving and countertops.
Corbels can be added to the bottoms of a countertop or a wall cabinet to provide a decorative touch. Since most cabinets and countertops, whether wall or base cabinets, already have secure mounting, most of the time, a corbel is a motif on a finished cabinet. The result is that corbels are ornamental in most kitchens, rather than plain, and can be sculptural to add elegance to the interior.
