Our 135° rotation set (30*80) is a hardware kit that allows for the attachment and rotation of two objects at a 135-degree angle. The set typically includes two components, one with a rectangular shape and the other with a rotating mechanism. The rectangular component is designed to be mounted onto a flat surface, such as a wall or ceiling, using screws or other types of fasteners. The rotating mechanism allows for the attachment of a second object, such as a shelf or panel, which can then be rotated to a desired angle using the set. The rotation mechanism typically includes bearings or other types of moving parts, allowing for a smooth and effortless rotation. The 135° rotation set is commonly used in a variety of applications, such as in the creation of storage solutions, displays, and other types of structures that require the ability to rotate attached components. With their sturdy construction and ease of use, 135° rotation sets provide a reliable and convenient solution for any application that requires a rotating attachment.
