*For choker applications, the working load limit must be reduced by 20%. The Crosby A-1338 cradle grab hook doesn’t require any reduction of the working load limit. The design factor of 4:1 on Spectrum 10 alloy chain agrees with the design factor used by the International Standards Organization (ISO) and ANSI B30.9 and is the preferred set of working load limit values to be used.

All Grade 100 fittings shown below can also be attached to Grade 80 chain.

How To Order

The following information should be given on orders or inquires for chain slings.

  • SIZE: This is specified by the size of the material from which the chain is made, determined by working load limit required.
  • REACH: This is the length, including attachments, measured from bearing point to bearing point.
  • TYPE: Select and specify proper type of sling from list shown. Examples: S = single; O = oblong link; S = sling hook
  • ATTACHMENTS: Unless otherwise specified standard master links as given herein will be used. When other than standard master links or hooks are required, we should be given a complete description or a drawing of the requested substitute.

When hot galvanizing is specified our recommended working load limits must be reduced.
Please contact us with all such inquires.
