What is the rated capacity of 1/2 inch tubular nylon?

• A. 6,250 lbs
• B. 1,000 lbs
• C. 500 lbs
• D. 12,500 lbs

Answer: (B)

Rated capacity, or working load limit, is the safe load a rope or strap is intended to carry in use. For 1/2 inch tubular nylon, the established safe working load in this context is about 1,000 pounds. This rating provides a margin below the rope’s breaking strength to account for knots, wear, angle loading, and dynamic forces that can occur during use. The other numbers would imply much higher capacities than this size and material typically provides, so they aren’t used for a 1/2 inch tubular nylon in standard Air Assault training. Therefore, 1,000 pounds is the correct rating to rely on.
