Grade 80 is a high strength, heat treated alloy chain that is primarily used as a sling component for overhead lifting, but can also be used in rigging and tie down applications where a lighter weight, high strength chain is desirable. Grade 80 is recommended for lifting by NACM, ANSI and OSHA. Manufactured from special analysis alloy steel, Grade 80 is engineered for a superior combination of strength, lightness and durability. All lifting slings and assemblies sold by Acme Rigging will have a durable metal, OSHA required, identification tag attached to the sling listing:

- Size
- Grade
- Date of assembly
- Number of legs
- Serial number
- Reach
- Working load limit (at specific angle of lift)
