A typical harness for rope work is made of __________ which has a breaking strength of ______ to ______ lbf.

• A. webbing components; 6,000 to 9,000 lbf
• B. buckles; 4,000 to 6,000 lbf
• C. D-rings; 7,000 to 9,000 lbf
• D. equipment loops; 5,000 to 7,000 lbf

Answer: (A)

Rope-work harnesses rely on woven webbing for the straps that distribute the load across the body. The breaking strength of these webbing components is typically in the 6,000 to 9,000 pounds-force range, reflecting the material (often nylon or polyester) and the weave used to withstand dynamic loads during a fall. Hardware like buckles, D-rings, and equipment loops matter for fit and attachment, but they’re usually designed to handle higher loads and don’t define the harness’s overall breaking strength unless they’re damaged. That’s why the main emphasis is on the webbing’s strength—the straps and their stitching—when considering how the harness will behave under load. This is also why regular inspection focuses on wear, cuts, and compromised stitching in the webbing, since that’s where failure is most likely to occur.
