A ball chain is a chain which consists of small steel balls connected via short segments of wire.
Ball chain is commonly used to wear dog tags and keychains.
The chain is made of stainless steel and withstand quite heavy tensile.
The item is delivered in a set of two chains of different lengths – 23 5/8 inch and 2 7/16 inch.
The balls are hollow and have two small antipodal holes. The holes accept a short segment of wire warped at the end, as a rivet, so that the end is bound inside the ball. The wire is then samely connected to another ball. The balls and wires are joined together to form a chain. Due to this method of connection, the chain can rotate about its axis unrestrictedly, which helps to prevent kinking.
The ordinary ball chain accessories are connectors. Each end of a connector can surround a ball at the end of a chain and pawl its wire connection, which holds it firmly. Connectors are used to link two lengths of chain together, or to connect the ends of the same chain to form a noose.
The connectors do not require any tools to apply or remove and are interchangeable.
