What does nominal length mean ?

Nominal length refers to the designated or intended length of a particular object or component. It is a standard or approximate measurement that is used for identification, categorization, or communication purposes. In many cases, the nominal length might not precisely match the actual or physical length due to manufacturing tolerances, variations, or other factors.

For example, in the context of rigging and lifting equipment like slings, straps, or cables, the nominal length could refer to the length that the manufacturer designates for a specific product. This helps users select the appropriate equipment for their needs. However, the actual length of the item might vary slightly due to factors such as sewing allowances, variations in materials, or other manufacturing considerations.

It's important to be aware of the nominal length when selecting or using equipment, but always refer to the manufacturer's specifications and guidelines for accurate measurements and safe usage.
