Corner brackets are L-shaped metal or plastic pieces used to reinforce the corners of furniture, shelves, and other structures. They provide stability and support, helping to prevent joints from separating or collapsing over time. Corner brackets are commonly found in DIY projects and construction, making them essential for both professional builders and hobbyists. These brackets come in various sizes and materials, allowing for versatility in different applications. They can be easily attached using screws or nails, making installation straightforward. Corner brackets are often used in conjunction with other hardware, such as screws and wood glue, to enhance the strength of the assembly.
