What is the rope diameter for the 25K sling set?

• A. 7/8 in
• B. 1 1/4 in
• C. 1 in
• D. 1 1/2 in

Answer: (B)

The key idea here is that the sling set’s load capacity is matched to a specific rope size. For a 25K (25,000-pound) sling set, the rope must be thick enough to provide the required strength while still fitting the hardware and rigging components. The standard choice for this set is a rope diameter of 1 1/4 inches. That size delivers the necessary tensile strength and appropriate clearance for the fittings and clamps used with the 25K hardware. Using a smaller diameter would risk an inadequate working load limit, while a larger diameter would add unnecessary weight and may not fit the hardware properly. So, 1 1/4 inch is the established specification for the 25K sling set.
