A curb chain is a chain which is created from round or oval interlocking links which are twisted until they are flattened out. Sometimes the links are fed through a rolling mill to create a true flat chain. There are many varieties depending on openness of links and shape. This type of chain can be interlocked with other link styles (as a figaro chain).
Curb chains can be either hollow or solid.
Synonyms: Gourmette chain.
