  • Hooks are forged with a greater cross sectional area that results in a stronger hook with better fatigue properties.
  • Modified UNJ thread on end fittings for improved fatigue properties. Body has UNC threads.
  • Turnbuckle eyes are forged elongated, by design, to maximize easy attachment in system and minimize stress in the eye. For turnbuckle sizes 1/4” through2 1/2”, a shackle one size smaller can be reeved through eye.
