18.4.3 Terminal Fittings and Master-Links
A range of terminal fittings may be attached directly onto the sling legs. Examples of typical terminal fittings are links, hooks and shackles. The seating where the rope rests on the fitting should be smooth and not have sharp edges which might cause damage to the rope. Ideally, the seating should have a diameter of not less than twice the diameter of the rope and in no case must it be less than the diameter of the rope.
