A Turnbuckle is a mechanical device used to adjust the tension or length of a rope, cable, or other tensioning elements. It consists of two threaded components, typically with eye bolts or hooks at each end, which are screwed into a central body. The central body is a cylindrical part that can be rotated to either tighten or loosen the tension between the two ends. Turnbuckles are commonly used in rigging, construction, marine applications, and other industries where precise tensioning of cables, wires, or ropes is required.
By rotating the turnbuckle's central body, the distance between the two ends is either increased or decreased, which adjusts the tension in the connected components. Turnbuckles can be made of different materials such as steel, stainless steel, or aluminum, depending on the strength and corrosion resistance required for the application.
