Overall there is a huge variety of climbing ropes available for different purposes; for instance, there are well over one hundred different dynamic single ropes (the most popular rope system in climbing). [3] Kernmantle ropes are still used in sailing and other sports, but the technical requirements are usually not as rigorous for such purposes ...
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 ...
Greater elasticity allows a dynamic rope to more slowly absorb the energy of a sudden load, such from arresting a climber's fall, by reducing the peak force on the rope and thus the probability of the rope's catastrophic failure. A kernmantle rope is the most common type of dynamic rope now used.
Rope compatibility: 9 to 12 mm low stretch kernmantle rope; Replaceable aluminium bobbins (main bobbin with stainless insert) Carabiner slot that can accept normal carabiners and Petzl Freino braking carabiner; Short squeeze handle made from metal with red plastic cover; Ability to lock out the handle for one handed descents
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 ...
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 ...
