Door handles are the most direct interaction component between users and doors. Basic operations such as opening, closing, and locking doors can be easily completed through rotating, pulling, or pressing actions. Featuring a black color scheme and a finely finished surface, this lock harmonizes well with dark or modern wall surfaces. Its compact structure and durable metal components subtly showcase exquisite craftsmanship and a premium feel. The lock is completely embedded within one side of the door, with no locks or handles on the outer side, achieving a seamless visual integration with the background wall or cabinetry. When closed, only a narrow gap is visible, creating a minimalist and discreet spatial effect. A locking knob or keyhole is located only on the inside, preventing direct opening from the outside. It provides basic partitioning and security for secret rooms, private storage rooms, or rooms requiring completely concealed entrances, enhancing spatial privacy. Designed specifically for special door types such as French doors, hidden doors, and concealed doors within background walls. Supports inward/outward opening methods, adaptable to door thicknesses of 35-50mm, ensuring smooth and concealed door movement after installation. Through its completely concealed entrance design, it cleverly divides space, creating secret rooms, hidden studies, or storage areas. Its concealment adds a sense of exploration and design ingenuity to home or commercial spaces., Manufacturer: Zxarunas
