6.0 Rappel Cord 2015
Accessory cord developed specially for rappelling maneuvers. The high aramid content provides the required strength and safety. The 6.0 Rappel Cord is also distinguished by a low stretch that assists with rappelling. It is not suitable as a safety rope for mountaineering or climbing.

Hi Fin, It is normal when buying a static rope to be given some indication of its elongation under a given load. Mammut for example list an "impact force" on their static ropes. However, no such rating is given for the rappel cord suggesting that it is more dynamic than their fully static ropes. The rope has been woven with polyester to increase it's stiffness, however it has also been left with some stretch in order to help with rappelling. Overall, you should expect the stretch of the rappel cord to be somewhere in between a normal climbing rope and a fully static rope. Hope that helps, Dave
