Compliance to the above specifications is based upon testing according to the Cordage Institute Standard Testing Methods for Fiber Rope and/or ASTM D-4268 Standard Methods of Testing Fiber Ropes. Weights: Are approximate and may vary Tensile Strengths: Are approximate average for new, unused ropes. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 10% (Cordage Institute defines minimum tensile strength as two standard deviations below the average tensile strength of the rope.).

Very little degradation from UV Can be used outside over long term if inspected regularly.

Good resistance to most minerals/organics, acids, and weak alkalies. Excellent resistance to bleaches and other oxidizing agents and to most solvents.

Polyester’s melting point is 480°F with progressive strength loss above 300°F. UHMWPE melting point is 300°F with progressive strength loss above 150°F,

Polyester and the Dyneema® core fiber have good resistance to passage of electrical current. However, dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is used in proximity to live circuits.

Recommended D/d* ratio is 8:1.

EnduraBraid: White, Blue Tweed, Red Tweed, Green Tweed Endura 12: Coated Clear, Red, Blue, and Grey

Working Loads:
No blanket working load recommendation can be made because it depends on the application and conditions of use, especially when the potential for danger to personnel exists. It is recommended that the user establish working loads and safety factors based on professional and experienced assessment of risks.

The working load is a guideline for the use of a rope in good condition for non-critical applications, and should be reduced where life, limb, or valuable property is involved, or for exceptional service such as shock, sustained loading, severe vibration, etc. The Cordage Institute specifies that the Safe Working Load of a rope shall be determined by dividing the Minimum Tensile Strength by the Safety Factor, Safety Factors range from 5-12 for non-critical uses.
