Both Working Load Limit columns are published by the manufacturer for this part — neither is calculated by us. The 5:1 figure is the conservative one and the rating to design to. Pound figures are converted by SlingCenter from the manufacturer’s metric rating at 1 kg = 2.20462 lb and rounded down — a unit conversion only, not a change of rating. The metric figure is the rating of record. Size is the manufacturer’s nominal trade size and does not change between unit views — this part is ordered and stamped by that size in every market; the millimetre figure beside it is the equivalent, not a different size. A column shown without a unit carries a designation rather than a measurement — a thread callout or a part type — so it reads the same in both views.

Inspection & Safety
