Internally Threaded Turnbuckle-Style Connecting Rods

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension. Add right- and left-hand threaded rod ends to build your linkages. Rods have a hex-shaped body so you can adjust them with a wrench.

Note: The end with the left-hand threads is marked with a groove.

Carbon Steel—Carbon steel rods generally handle higher loads than aluminum and stainless steel rods.

18-8 Stainless Steel—18-8 stainless steel rods have good corrosion and chemical resistance.

Aluminum—Aluminum rods are lightweight and have good corrosion resistance.

Closed-Body Clevis-to-Wire Rope Turnbuckles—For Lifting

Use these turnbuckles in lifting applications with wire rope. Their closed body not only protects threads from damage and debris, but also keeps these turnbuckles slim enough to fit in tight spaces.

To install, fray the end of the wire rope with a marlin spike and screw the socket over the plug. You'll know the wire rope is secure if you see wire strands through the inspection hole on the turnbuckle body. Use an assembly kit (not included) to support the wire rope while you drive the plug into the wire rope end.

Warning: Turnbuckles must match rope diameter and be installed correctly to obtain maximum holding power. Test all assemblies for required strength before use. Do not use with coated rope unless the coating is removed.

Note: Capacities listed are for vertical lifting only.
