Turnbuckle

A turnbuckle is a mechanical tool used to tighten, pull, or adjust the tension of a cable, chain, or wire in a precise and secure manner. It generally works using a lever or screw system, allowing elements to be brought together or held in place without excessive effort. Robust and practical, it is commonly used for guy wires, fences, construction site installations, temporary structures, or any assembly requiring reliable tension adjustment.
