Product Overview

Calibration marks for precise adjustment and tuning of rig tension.

Allow accurate and repeatable settings of rig tension and precise adjustment, using an easy-to-read scale on the side of the turnbuckle barrel. Instead of turning a stud or turnbuckle body between two ends, you make a single adjustment on a coupling nut, which allows finer adjustment and more tension on the wire than with a normal turnbuckle. An integral toggle prevents off-axis loads on either the wire or turnbuckle body. Machine swage fitting at upper end. 316 Stainless steel bodies and terminals. Nickel-plated bronze coupling nuts.
