KM-III’s 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 with exceptional UV resistance. KM-III is NFPA and CE approved, and comes with an NFPA certification tag and CE labels. This is one of the most durable static ropes available with the handling and knotability you expect from New England. The sheath is braided with 32 bobbins to provide an optimum sheath/core ratio. This allows for an incredibly smooth sheath, higher tensile strengths, and superior handling characteristics.
