Mending plates are metal plates that are used to join two pieces of wood or other materials together. They are typically made of steel or other metals and are available in various sizes and shapes to accommodate different applications. Mending plates are often used in furniture making or woodworking to repair broken or weakened joints between two pieces of wood. They can also be used to connect two pieces of wood that are not touching, such as in a bookshelf or cabinet. Mending plates are commonly installed using screws or nails, and they should be positioned in a way that provides the maximum support and reinforcement. Proper installation of mending plates is crucial for the overall strength and stability of the structure or furniture piece. Mending plates are an important component in building and woodworking and can greatly improve the longevity and durability of the finished product.
