Wedge sockets are rated at approximately what percentage of the rope's breaking strength?

• A. 50%
• B. 75%
• C. 85%
• D. 95%

Answer: (B)

Wedge sockets are designed to terminate a rope while providing a reliable working load that accounts for the weakening effects of the termination. The rope fibers are compressed and bent where the rope sits in the socket, and friction and the clamp action reduce the rope’s effective strength compared to a rope under a straight, bare load. To provide a safe, practical working load, manufacturers rate wedge sockets at about three-quarters of the rope’s breaking strength. So the best answer is that the rated working strength is roughly 75% of the rope’s breaking strength. If the rope’s breaking strength were 10,000 pounds, for example, the wedge socket would typically be treated as safe up to about 7,500 pounds under normal use. This balance avoids overstressing the termination while not being unnecessarily conservative.
