Wire rope can be measured from termination points such as tips, eyes, loops, or tabs. For example, a wire rope is commonly measured from the bearing of an eye to the opposing eye (also called eye-to-eye), or loop-to-loop. Measurement is taken from the top inner center of the loop or eye. Wire rope can be pre-fashioned, to include established lengths, such as 50-feet, or 100-feet, and end fittings such as steel stops (ferrules), studs, or choker knobs. Measurement is taken from tip to tip (outer end of the rope) or from the end of the fitting.
