Corbels are ornamental brackets or projections that support the weight of overhanging structures. In decorative plaster mouldings, corbels are often used for aesthetic purposes rather than structural support. They can be strategically placed to add visual interest and highlight specific architectural features. Corbels come in various shapes and sizes, offering versatility in design. Homeowners can use corbels to accentuate features such as fireplace mantels, shelves, or doorways, contributing to an overall sense of elegance and craftsmanship.
