New England KM III Static Ropes

UL Classified to NFPA 1983 General Use, EN 1891 A

KM-III static kernmantle rope is an exceptional static rope for rappelling, caving, rescue, top roping, fixed rope applications, hauling and life-safety applications. The unique polyester sheath differentiates KM III from other static ropes. The polyester sheath is balanced with a nylon core to limit rotation, bouncing and stretch. Ropelab tests demonstrated polyester sheaths significantly outperformed nylon in abrasion tests. Each piece of KM III rope comes with an NFPA certification tag and CE labels. Thirty-two bobbins provide the correct sheath for the unique demands of static rope and the optimum sheath/core ratio. This allows for an incredibly smooth sheath, higher tensile strengths and superior handling characteristics.
