Notes:
(1) Other grades of proof tested steel chain include Proof Coil (Grade 28), Hi-Test (grade 43 Chain, and Transport (grade 70) Chain. These grades are not recommended for overhead lifting and therefore are not covered by this standard.
(2) Rating of multi-leg slings adjusted for angle of loading between the inclined leg and the horizontal plane of the load.
