This pivot hinge is designed to support hidden door configurations by enabling a door to rotate a full 360°. It works for concealed entries such as jib doors, bookcase doors, bookshelves, secret doors, or hidden rooms, providing a functional mechanism without visible hinge lines. Made from stainless steel, the hinge resists rust and corrosion while offering stable performance for wide or heavy doors. Unlike traditional side-mounted hinges, this model is mounted at the top and bottom of the door, a setup that contributes to greater strength and reduces sag over time. The hardware is built to handle up to 100 kg (220 lbs.), allowing use on larger or wider doors where reliable support matters. Installation materials include clear diagrams and measurements to guide placement, supporting precise alignment during setup. A step-by-step video tutorial is available to assist with mounting and verification, helping to minimize guesswork and misalignment. The combination of a robust metal construction and top-and-bottom mounting geometry aims to provide a durable option for customized door projects. When planning a concealed entry, consider the doorway dimensions and load requirements to determine if this pivot hinge meets the desired specifications. Proper installation is essential to maintain smooth rotation and door stability over time.
