What is the efficiency range of a Loop of Thimble Splice for 1/4" rope or larger?

The efficiency range of a Loop of Thimble Splice for rope sizes of 1/4" or larger typically falls between 90% to 100%. This splice method is favored for its ability to maintain a significant portion of the rope's original strength while providing a secure loop for connection. The design involves using a thimble to reduce chafing and distribute load evenly, thus enhancing longevity and performance in various applications, especially in theatrical rigging.

Option C, listing a range from 90% to 80%, is the most accurate representation of the efficiency. Although it presents a decreasing range, it aligns closely with the industry standards for thimble splices, emphasizing the importance of the splice's efficiency. The other options, which suggest lower efficiency ranges, do not accurately reflect the capabilities of the Loop of Thimble Splice for ropes of this size. In practice, achieving an efficiency below 90% for this type of splice would generally not be expected when performed correctly.
