Hidden hinges, also known as concealed hinges, are hardware components used to attach doors or cabinets to their frames while remaining out of sight when the door is closed. This design provides a clean and seamless appearance, making them popular in modern furniture and cabinetry. These hinges allow for smooth operation and can support heavy doors without being visible. They are often adjustable, enabling precise alignment and ensuring that doors close properly. Hidden hinges are commonly found in kitchen cabinets, wardrobes, and office furniture, enhancing both functionality and aesthetics.
