- Round link chains for general purposes, caliber from 19 to 42 , TU U 01124980-032-2000.
- Chains with a jumper anchor mooring.
Round link chain is supplied in coils or in pieces. Each piece has a length of 5, 10, 25 m. Round link chain coils can have different lengths.
Round link chains can be made of low-carbon steel, stainless steel, as well as special steel, which increases the strength of the round link chain .
