When rigging longer spans or high-capacity cables, you need maximum tensioning power.

Drop-forged from solid carbon steel and hot-dip galvanized for extreme weather resistance, its extended 18-inch body provides over 12 inches of active tensioning travel—allowing you to easily eliminate cable sag on 150ft to 500ft backyard and commercial zip line runs.

❓ Frequently Asked Questions
Q: When should I choose a 1/2" turnbuckle over a 3/8" turnbuckle?
A: Choose the 1/2" turnbuckle if your zip line run is 150 feet or longer, uses 5/16" or 3/8" wire rope, or supports adult riders up to 350 lbs. The longer 18" barrel gives you significantly more tensioning travel to eliminate sag on extended spans.
Q: How do I adjust this turnbuckle once installed?
A: Place an adjustable wrench or metal rod through the center barrel opening and rotate. Turning one direction draws both jaws inward simultaneously to tighten your cable.
Q: Can this turnbuckle remain outside all winter?
A: Yes! The hot-dipped galvanized finish meets ASTM A153 outdoor standards and is designed to resist rust and freezing conditions year-round.
