What does the size number of a roundsling indicate?

The size number of a roundsling refers specifically to the relaxed diameter of the sling. This measurement is important as it helps users determine the appropriate application and environment for the sling. The relaxed diameter indicates how thick the sling is when it is not under load, which can influence the sling’s flexibility and its compatibility with various lifting hooks or hardware.

When selecting a roundsling, knowing the relaxed diameter can aid in ensuring proper handling and fitting during lifting operations. For example, a sling that is too thick may not fit securely into the hooks or other rigging mechanisms, leading to safety hazards.

In contrast to the correct answer, actual dimensions of the sling would encompass length and width while weight capacity describes how much weight the sling can safely lift. The type of material used is also an important aspect of the sling, but it is not directly indicated by the size number.
