- For lifting with chains and synthetic slings, with Grade 100 lifting components.
- Working load limit by size: 6mm 1.4 tonne, 8mm 2.5, 10mm 4.0, 13mm 6.7, 16mm 10.0 tonne.
- The table also lists the breaking load (BL), four times the WLL in every size: for example 16.0 tonne for the 10mm hook.
- Each one is marked with CE, its WLL, a trace code linked to its test certificate, and the maker's mark.
