Concealed hinges, also known as hidden hinges, are hardware components used to attach doors to frames while remaining out of sight when the door is closed. This design provides a clean and streamlined appearance, making them popular in modern cabinetry and furniture. They allow for smooth door operation without visible hardware disrupting the aesthetic. These hinges are typically adjustable, enabling precise alignment of the door for optimal functionality. They come in various sizes and styles to accommodate different door types and thicknesses. Concealed hinges are commonly used in kitchen cabinets, wardrobes, and office furniture for a sleek finish.
