Which material is preferred for tag lines due to its flexibility?

The preferred material for tag lines due to its flexibility is fiber. Fiber materials, such as synthetic fibers or natural fibers, are commonly used because they offer excellent flexibility and durability. This flexibility allows the tag line to easily adapt to various lifting and positioning tasks, improving the safety and efficiency of line work.

While silk is known for its strength and lightweight characteristics, it does not provide the same level of flexibility needed for a tag line in a utility context. Cotton, although flexible, can absorb moisture and may not be as durable when subjected to heavy use or harsh environmental conditions. Raffia, on the other hand, is generally less robust than fiber options and does not provide the same level of flexibility and strength required for reliable tag lines in lineman tasks.
