Utility Stringing Lines 12 Strand Ropes

Aramid-12

Made with 100% heat and abrasion resistant Aramid fibers, Aramid 12 can reduce the diameter requirements to decrease weight and storage space.

Nylon-12

Made with 100% high strength nylon it will flake into smaller areas than most ropes. Uses include mooring pendants, stage rigging, control lines, high strength with shock absorption. Meets CI-1312.

Polyester-12

Made of 100% Polyester, it is a high strength with low stretch. Uses include tension stringing, winches, tower erections, transformer slings, general construction. Meets CI-1305.

HMPE-12

Made with 100% HMPE fiber, very high strength and light weight. Coated with Tuff Coat Urethane. Uses tension stringing, winches for trucks, and ATV. Meets CI-1908.

Rope Safety Considerations

New Rope Tensile Strengths: New rope tensile strengths are based on tests in accordance with ASTM Test Method D-4268 on new and unused rope in laboratory condition.

Working Loads: Working loads are for rope in good condition with approximate splices, in non-critical applications, under normal service conditions. Working loads should be exceeded only with expert knowledge of conditions and professional estimates of risk. Working loads should be reduced where life, limb, or valuable property are involved, or for exceptional service conditions such as shock loads, sustained loads, etc.

The Cordage Institute specifies that the Safe Working Load of rope shall be determined by dividing the Minimum Tensile Strength by the Safety Factor. Safety factors range from 5 to 12 for non-critical uses.
