Eye-Eye Turnbuckle

The eye-to-eye turnbuckle tensioning device consists of a body in open or closed design and two ring-shaped hooks on a threaded rod. Opposite ends of the sleeve have holes with internal opposite-direction threads: one of the screw-in elements has a right-hand thread, the other a left-hand thread.

The main material for manufacturing eye-to-eye turnbuckles is carbon steel. The finished products undergo galvanic zinc plating for corrosion protection, since they most often work outdoors.

The operating principle of the tensioner is the opposing movement of the ring screws when the sleeve is rotated. To loosen the connection, rotation is performed in the opposite direction. Used for tensioning cables and in setting up guy wires.

Eye-to-eye turnbuckles are produced with a wide range of working rod diameters, each rated for a specific load. Thin rings withstand small forces, while the most powerful can hold the stays of an automobile bridge. Like other types of turnbuckles, this rigging device design is not used for lifting or lowering loads.
