turnbuckle

A turnbuckle is a device used to adjust the tension or length of ropes, cables, or wires. It consists of two threaded metal fittings connected by a frame; when you rotate the frame, both fittings either draw closer together or move apart, allowing precise tightening or loosening. Turnbuckles are commonly used in situations like rigging, sailing, or construction to ensure stability and proper tension. They are valued for their ease of adjustment and secure hold, making them essential for maintaining structural integrity and safety in various applications.
