Which item connects cables and provides means of adjusting cable tension?

• A. Turnbuckle
• B. barrel
• C. cable terminals
• D. secured

Answer: (A)

A turnbuckle connects cables and provides a means of adjusting tension by using a movable central body with threaded ends. When you rotate the body, the two end fittings move closer together or farther apart, lengthening or shortening the cable assembly and thus increasing or decreasing tension. The ends attach to anchor points or other fittings, allowing precise tightening to keep lines taut and stable. A barrel is just a cylindrical piece without adjustment capability, cable terminals are end fittings that connect but don’t change tension, and “secured” isn’t a device for tensioning. So the turnbuckle is the component that both connects and lets you fine-tune cable tension.
