Braided nylon rope, having excellent strength and shock absorbing properties, is used in a number of fall protection systems.
Solid braid nylon is used in work line and rescue line assemblies in chair type descent systems. It is very popular as flagpole halyard, often with an aircraft cable core to minimize stretch and to prevent vandals from cutting the flag down.
Diamond braided cord and twine are used in the manufacture of netting for use as barrier netting, in fall protection systems, and in products such as tennis nets, cargo lifting systems, and helicopter slings. These are mostly 8 carrier through 32 carrier constructions. In smaller sizes, popular nylon diamond braids include venetian blind cords, parachute cords, lacing lines and utility cords.
Double braided nylon is used in vertical lifeline systems, as accessory cords, and in positioning lanyards by tree care, window washing, and rigging contractors. It is also used to make slings and as personal safety line.
Nylon Kernmantle - a construction with parallel yarns covered by a very thin diamond braided nylon cover - is used by tree care contractors as haul rope, accessory cord, and prusick cord.
(a) - Nylon ropes have poor dielectric properties, that is, they are more likely than polyester or polypropylene ropes to absorb water and conduct electrical current. Nylon ropes should not be used when doing tree trimming or other work near power lines.
(b) - The same properties that make nylon a good choice for fall arrest systems make it a poor choice for pulling applications. Because it tends to stretch and quickly recover, it can snap back and cause injury if used to pull wire or cable, for tug of war, or for similar activities.
