Rescue Knot Efficiencies

knot14Prompted by increasing inquiries regarding the durability and attributes of 11 mm NFPA General Use Rope, our friends at CMC (Instructors LeRoy Harbach and John McKently) embarked on a sequence of experiments within the CMC lab. Their investigation into knot effectiveness encompassed 487 trials across various rope varieties, uncovering valuable insights into the influence of diameter, composition, and materials on knot performance. Additionally, they broadened the focus of their research to assess the viability of smaller diameter ropes suggested for rescue operations, leading to the formulation of guidelines for estimating knot efficiency relative to rope diameter.
