Which rope is constructed by twisting 3 strands and used for static belays and lobster claws?

• A. Hawserlaid Rope
• B. Kernmantle Rope
• C. Dynamic Rope
• D. Headwall Harness

Answer: (A)

Rope built by twisting three strands is hawser-laid rope. This three-strand construction creates a sturdy, relatively stiff line with low elongation, which is ideal for static belays and anchor setups where you want minimal stretch under load. It’s the kind of rope you’d see used in fixed-line rigging and rescue scenarios, where reliable, non-stretch performance matters—think of attaching and holding gear in place during rappels or anchor work like lobster claws. Kernmantle rope, by contrast, is a modern design with a core and a woven sheath; it can be made for static or dynamic use but isn’t defined by a three-strand twist. Dynamic rope intentionally stretches to absorb fall energy, which is not the goal for static belays. And Headwall Harness isn’t a rope at all.
