CMC Rescue New England Ropes KM III, 1/2" (price per foot)

A superior handling rescue rope, New England Ropes KM III static kernmantle rope features composite construction, with the continuous filament polyester sheath braided over a continuous nylon fiber core.

Featuring a weight-balanced construction with the sheath and the core each representing half the total weight, KM III is torque-balanced to eliminate any spin during a rappel. This provides excellent handling and knot-holding characteristics, as well as rugged protection from abrasion and cutting.

The polyester sheath provides added protection from ultraviolet light and chemicals harmful to nylon, while reducing the strength loss and weight gain that occurs when nylon absorbs water.

*Rope is sold by the foot. Please contact customer support for maximum length available.
