Abstract : The current technique of using multiple layers of flat nylon webbing for construction of extraction lines has proven to require considerable detail to fabricate, is unwieldy in large sizes, and does not have a long service life. Multiple layered extraction lines when bent over connecting hardware pins fail to achieve uniform loading throughout the plies. Therefore, additional plies are needed to compensate for the strength loss. These deficiencies have promoted an investigation into using commercially available nylon double braided rope as extraction lines. This report describes the various tests performed on the nylon rope which project some operational advantages and indicate suitability of the nylon double braided rope extraction line. It is recommended that braided nylon 2-in-1 rope replace the flat nylon webbing for use as extraction lines. (Author-PL)
