What is a turnbuckle?

A turnbuckle is a device used to adjust the tension or length of ropes, cables, tie rods, and other tensioning systems. It typically consists of two threaded eye bolts with a central body that can be turned to either shorten or lengthen the distance between the eye bolts. The turnbuckle is often used in applications such as construction, shipbuilding, and automotive repair to tighten and secure various components. Turnbuckles come in various sizes and materials, including steel, stainless steel, and aluminum, to suit different load requirements and environmental conditions. They are usually easy to install and provide a simple yet effective method for adjusting tension in a wide range of applications.
