Kernmantle rope (from German kern 'core' and mantel 'sheath') is rope constructed with its interior core protected by a woven exterior sheath designed to optimize strength, durability, and flexibility. The core fibers provide the tensile strength of the rope, while the sheath protects the core from abrasion during use. This is the only ...
Lighter, thinner ropes, however, have less strength than a thicker rope and will sustain fewer hard falls. Note that some belay devices are better suited for different rope diameters. This is particularly relevant with assisted braking devices, such as the Petzl Grigri (which, for example, works best with a 9.4-10.3 mm thick line [1]) or the ...
Although ropes made of natural fibres such as hemp and flax were used in the early days of alpinism, [1] modern climbing uses kernmantle ropes made of a core of nylon or other synthetic material and intertwined in a special way, surrounded by a separate sheath woven over it. The main strength of the rope is in the core, and the sheath of the ...
Parachute cord (also paracord or 550 cord when referring to type-III paracord) is a lightweight nylon kernmantle rope originally used in the suspension lines of parachutes. This cord is now used as a general purpose utility cord. This versatile cord was used by astronauts during the 82nd Space Shuttle mission to repair the Hubble Space ...
Some climbers will use a single full-thickness climbing rope with a diameter of approximately 9 to 11 mm (0.35 to 0.43 in), and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8 to 9 mm (0.31 to 0.35 in) to ...
5 things I care about How the Chiefs win the AFC West. In a way, it’s hard to muster the energy to care about a ninth straight AFC West title for the Kansas City Chiefs.
Rope rescue is a subset of technical rescue that involves the use of rope, be it steel or cable rope, or more commonly used nylon, polyester, or other type of rope. Kernmantle (kern = core and mantle = sheath) rope as it is called, is available in various types: dynamic (stretches to absorb the shock of a falling lead climber or rescue ...
