Semi-concealed inset hinges are a type of hinge that is installed into the door or cabinet, but only partially visible from the outside. They are typically used on cabinet doors, but they can also be used on furniture doors and other applications. They typically have two parts: a barrel hinge and a mounting plate. The barrel hinge is attached to the door, and the mounting plate is attached to the cabinet. The mounting plate is inset or stepped down to accommodate the cabinet door.
