Butt hinges are a type of hinge commonly used in doors and cabinets. They consist of two plates, or leaves, that are attached to the door and the frame, allowing the door to swing open and closed. These hinges are typically made of metal and come in various sizes and finishes to match different styles and applications. The design of butt hinges allows for a clean and unobtrusive look, as they are often installed flush with the surface of the door and frame. They provide strong support and durability, making them a popular choice for both residential and commercial use.
