What does a turnbuckle body do?
The body is the heart of a turnbuckle. Because one end is right-hand threaded and the other left-hand, turning the body screws both end fittings in or out simultaneously, taking up or letting out slack to tension a line without twisting the cable. Buying the body separately lets you assemble a turnbuckle with the exact end fittings you need, eye, jaw, hook, or stub, or replace a worn body in an existing assembly. Match the body's thread diameter to your end fittings, and note the take-up length, the distance the fittings can travel to adjust tension, commonly offered in 6, 12, 18, and 24 inch take-ups. Keep the pull in-line, maintain thread engagement, and confirm the working load limit for the completed assembly. Choose 316 stainless for marine settings or hot dipped galvanized for durable outdoor use.

Turnbuckle Body FAQ
Why buy just the body?
To build a turnbuckle with your exact choice of end fittings, or to replace a worn body in an existing assembly.
What is take-up length?
The distance the end fittings can screw in and out of the body to adjust tension, commonly 6, 12, 18, or 24 inches. Match it to how much slack you need to remove.
How does the body adjust both ends at once?
One end is right-hand threaded and the other left-hand, so turning the body draws both fittings in or out together without twisting the cable.
