The Clevis Rod and the Turnbuckle Rod offer the ability to provide tensile strength by increasing their tension as they are tightened. The tightening is done by opposing left hand and right hand threads. In the Clevis Rod drawing shown below rotating the threaded rod overhand towards the installer it will draw the two Clevises closer, creating more tension. Rotate the Rod overhand away from the installer will move the clevises away from each other, relieving tension.
