Rope Size: Diameter and circumference are nominal. A new, unused rope in a relaxed state will measure larger; loading and use compacts ropes, sets splices, and lessens rope size. This is especially prevalent in rope sizes above 4" diameter. Published nominal sizes from 4-1/8" and larger represent stabilized or preloaded size.

Tensile Strengths: Tensile Strength determined in accordance with Cordage Institute 1500 Test Methods for Fiber Ropes and ISO 2307.
