The 15” sections of chain are long enough for most targets when used with the 60x60 gong stand and larger targets including the 12x20 and 18x30. The chain is 3/8" Gr100.
Grade 100 chain uses alloy steel heat treated to a higher hardness than Grade 70 which uses carbon steel. The Grade 100 is a good option for the 1/2” targets or any high use application. Don't confuse this with chain available at your hardware store. The highest grade available at most stores is going to be 70.
This is a great length for the 60"x60" gong stand.
The item includes two 15” lengths of chain.
