When determining sling leg length variation, how is the sling leg nylon rope measured?

• A. From inside eye to inside eye
• B. From outside eye to outside eye
• C. From knot to knot
• D. From end to end

Answer: (A)

Measuring sling leg length variation uses the distance between the inside faces of the eye openings, because that is the actual usable length of the leg that carries the load. The inside-to-inside distance excludes the thickness of the eye hardware and any knots or end pieces, which can change with wear and don’t represent the leg’s true working length. Measuring outside edges, knot-to-knot, or end-to-end would include those end components and give an inconsistent, misleading length. So, inside eye to inside eye provides a consistent, repeatable measurement for comparing sling leg lengths.
