The Grade 80 chain is the theatrical rigging alloy chain, also known as deck chain. The alloy properties improve the wear and tear that the chain will experience. Its strength makes it safe for overhead lifting and lifting slings.
Peerless Grade 80 Chain is excellent for theatrical rigging applications where adjustability is required. It comes in 6 lengths from 1' to 6'.
Grade 80 Chain vs Grade 70 Chain
Grade 80 chain is a heat-treated alloy steel chain whereas grade 70 one is a ''transport chain'' manufactured in heat-treated carbon steel (No alloying elements added to the steel). As the name suggests, grade 70 one is used as tie downs on over-the-road trailers so it’s also known as truckers chain. Unlike Grade 80, it can never be used for overhead lifting.
