Use a _____ to prevent the cable from tangling while it is being pulled.

• A. Swivel clevis
• B. Fixed hook
• C. Magnetic clamp
• D. Ratcheting pulley

Answer: (A)

When pulling a cable, twists in the pulling line can cause tangling and kinks as the line twists faster than you can unwind it. Using a device that allows the line to rotate freely as the load moves prevents those twists from transferring into the cable. A swivel clevis provides that rotating connection. It allows the hook or attachment to turn with the direction of pull, so the line can spin without twisting the cable. That freedom to rotate keeps the cable from tangling. The other options don’t offer that rotational relief. A fixed hook can’t rotate, so any twist is forced into the cable. A magnetic clamp holds securely but doesn’t accommodate rotation to relieve twist. A ratcheting pulley changes the pull direction and adds mechanical advantage, but it doesn’t inherently prevent tangling from twisting, unless the pulley itself is designed as a swivel, which the choice here does not imply.
