Key specifications

Selecting the right option

Select rigging screw configuration — jaw/jaw, jaw/swage, lag/swage — based on your end fittings. Jaw ends suit connection to shackles or chainplates; swage ends require a swaging tool or press for wire termination. Always use the supplied locking nuts, tightened against the body, to prevent the tensioner backing off.
