Butterfly hinges are a type of hinge that allows doors or panels to swing open and closed. They are named for their shape, which resembles a butterfly's wings when viewed from the side. These hinges are often used in applications where a full swing is needed, such as in cabinets, gates, or folding doors. Made from various materials like metal or plastic, butterfly hinges are designed to provide stability and support. They can be mounted on the surface or recessed into the material, making them versatile for different projects. Their unique design allows for smooth movement and easy installation.
