A turnbuckle is a mechanical fastening device used to adjust tension or length in cables, rods, wires, or tie systems. It is widely used in construction, structural bracing, rigging, fencing, electrical lines, marine applications, and industrial setups where precise tensioning and alignment are required.
The primary function of a turnbuckle is to tighten or loosen tension in a connected system. By rotating the body of the turnbuckle, the attached ends move closer together or farther apart. This allows controlled adjustment without removing or reattaching the connected components, making it an efficient and accurate tensioning solution.
