What is the efficiency rating of an eye splice?

The efficiency rating of an eye splice is typically recognized as 100%. This means that when a rope is spliced to create an eye, it retains its full strength, assuming the splice is done correctly. An eye splice is used when a permanent loop is needed at the end of a rope or cable, and one of its advantages is that it allows the rope to maintain its original strength, since there is no reduction in its capacity due to knots or other forms of termination. This makes the eye splice a highly effective and reliable method for creating a loop in various rigging and lifting applications.

In contrast, lower efficiency ratings like 75%, 85%, or even 95% would imply that the rope has lost some of its strength due to the method of termination, which is not the case with a well-executed eye splice. Proper technique and maintenance are critical to ensure that an eye splice reaches its maximum efficiency.
