Ball chain

Many of the balls and wires are joined together to form a chain.

Because of the connection method, the chain can swivel on itself unrestrictedly, which helps prevent kinking.

The connectors require no tools to apply or remove and are reusable.

[1] Other common accessories include other terminations similar to the connectors, but with a different connection on one end, such as a screw hole for semi-permanent affixing of a chain.

Typical width is size 3, or 2.4 mm, steel ball chain.
