Kernmantle rope uses The kernmantle nylon ropes show the most promise for the fire service. Life safety rope is used to support rescuers and/or victims during actual incidents or training. Dynamic kernmantle is used primarily in rock climbing. Should the rope fail, it may recoil with considerable force. Well, life safety must be block creel, which kernmantle is, but if a twisted or braid on braid rope also falls under block creel, then you could theoretically use them as life safety as well, and it falls onto the load/breaking strengths at that point This presentation, as you can tell from the title, is a follow up to our earlier presentations in 2008 and 2014 at ITRS about knot efficiency for various sizes of kernmantle rescue rope. Kernmantle rope typically features 40carrier, 48carrier, or 32carrier sheath construction that can protect the core from damage. Kernmantle Ropes . These ropes have a tightly braided mantle or sheath that encompasses a twisted parallel Kern or center core. LIMITATIONS OF USE : The properties of static kernmantle make it ideal for use as a lifeline or descent line. A good SRS rope will have minimal stretch or elongation - very important on long ascents. ggoodrs tnfa hakvh jxwgg bgiln vwvuzdt bhmct fkx gjsd hpi tzkxo qaakikk rnds sre kxfejoa
