A shelf bracket is a support device used to hold up shelves, allowing them to be mounted on walls or other surfaces. Typically made from materials like metal, wood, or plastic, these brackets come in various designs and sizes to accommodate different shelf weights and styles. They are essential for creating additional storage space in homes, offices, and retail environments. When installing a shelf, the brackets are attached to the wall, and the shelf rests on them. Proper installation ensures stability and safety, preventing the shelf from sagging or falling. Common types of shelf brackets include L-brackets, floating brackets, and decorative brackets, each serving specific aesthetic and functional purposes.
