Diameter of a 25K sling leg nylon rope?

• A. 3/4 in
• B. 1 in
• C. 1 1/4 in
• D. 7/8 in

Answer: (C)

The key idea is that the sling’s rated capacity scales with the rope’s diameter. For a nylon rope sling leg to be rated at 25,000 pounds, you need a diameter large enough to provide that strength, and standard sling-rating tables used in training show about 1 1/4 inches as the diameter that meets that 25K rating. This size reflects the material strength of nylon and how cross-sectional area governs pulling capacity. Smaller diameters would yield lower working load limits, while this 1 1/4 inch size is the commonly cited diameter that achieves the 25K rating. Always check the specific manufacturer’s charts and inspect the rope for wear or damage before use.
