What are the two main components of kernmantle rope?

• A. Block and Creel
• B. Core and Sheath
• C. Twist and Sheath
• D. Core and Creel

Answer: (B)

Kernmantle rope is built from two parts: a load-bearing core and a protective outer sheath. The core (the kern) carries most of the rope’s tensile strength, providing the actual support when the rope is loaded. The sheath (the mantle) surrounds the core, shielding it from abrasion, moisture, and dirt, and it also gives the rope its handling characteristics and durability. The two parts work together: the core provides strength, while the sheath protects and prolongs the rope’s life. If the sheath is damaged, the rope can wear more quickly or hide core damage, but the core is what ultimately determines whether the rope will hold under load.
