Which of the following correctly matches the tensile values for tubular and flat webbing as given?

• A. Tubular 4,000 lbf; Flat webbing 6,000 lbf
• B. Tubular 6,000 lbf; Flat webbing 4,000 lbf
• C. Tubular 3,500 lbf; Flat webbing 7,200 lbf
• D. Tubular 4,000 lbf; Flat webbing 4,000 lbf

Answer: (A)

The main idea here is knowing the typical tensile ratings assigned to tubular versus flat webbing in rigging. Tubular webbing is usually rated around 4,000 lbf, while flat webbing is stronger, commonly around 6,000 lbf, because of its construction and how the load is distributed across the width without the weaker seam points that can occur in a tubular tube.

So the pairing of tubular at 4,000 lbf and flat at 6,000 lbf matches what’s commonly specified, making it the best choice. The other options imply ratings that don’t align with the usual construction differences—for example, tubular being rated higher than flat, or both having the same strength—so they don’t fit typical standards.
