* Proof Load is 2.5 times Working Load Limit. Ultimate Breaking Load is 5 times Working Load Limit.

  • Hot Dip galvanized steel.
  • End fittings are Quenched and Tempered, bodies heat treated by normalizing.
  • Turnbuckle eyes are forged elongated, by design, to maximize easy attachment in system and minimize stress in the eye. For turnbuckles sizes 1/4" through 2 1/2", a shackle one size smaller can be reeved through eye.
  • Turnbuckle hooks are forged with a greater cross sectional area that results in a stronger hook with better fatigue properties.
  • TURNBUCKLES RECOMMENDED FOR STRAIGHT OR IN-LINE PULLS ONLY.
  • Modified UNJ thread for improving fatigue properties.
