Ball Chain Glossary

'A' Coupling · An attachment used to connect a ball chain to a bolt, screw, or rivet. Typically used for retaining purposes. Same general purpose as an end ring connector, but has two legs so that it is stronger but needs to be offset to become flush with the surface.

'A' Hook · An attachment that essentially combines an 'A' coupling with a C9 hook to form a single attachment that can be used for hanging signs, retaining small objects, or for a variety of similar applications.

Assembly · A custom built chain and attachment combination designed for a specific use.

'B' Coupling · An attachment similar in appearance to a connector but with a hole in the back that enables it to attach to a jump ring or to form an adjustable loop. Also used as a connector for chain sizes #10 and larger.

Connector · An attachment used to join both ends of chain or to splice together two separate chains. Used on chain sizes #1, #2, #3, #6, and #8 (for chain sizes #10 and larger, use a 'B' Coupling).

Crimp Cover · An open ball that is squeezed close on a jewelry chain to cover the connection point.

'D' Coupling · An attachment similar to an 'A' coupling in that it is used to connect a ball chain to a bolt, screw, or rivet for retaining purposes, but is more secure.

Deco-Tuf · A protective coating that enhances corrosion protection. A Ball Chain Manufacturing exclusive.

End Ring · An attachment that is permanently connected to the end of a ball chain to connect two different items.

End Ring Connector · An attachment with the same general purpose as an 'A' coupling in that it is used to connect a ball chain to an object, but slightly more lightweight because it has one leg instead of two.

Endless Loop · A chain formed together in a circle or continuous loop without using a connector.

Eyeletted · When the legs of an 'A' coupling are sealed together permanently at the hole.

Hank · A long length of unspooled ball chain.

Jump Ring · An attachment typically used to connect a ball chain to a small object such as jewelry charms. Also used for items such as drain plugs to that the plug can be pulled by the chain when in use.

Offset · When the legs of an 'A' coupling are bent at an angle of approximately 30 degrees.

Open Ball · A loose hollow ball in an open form. Open balls are often used as stop balls on electrical switches, roller shades, and as a more decorative alternative to a pendant on a pull chain. Open balls are also used for connecting two ends of chain in the jewelry industry.

Pendant · An attachment used to connect a ball chain to small items such as a pen or an electrical outlet cap for retaining purposes. Similar in appearance to a pendant, but better suited for retention of small objects.

Sleeve · An attachment used to connect a ball chain to small items such as pens or electrical outlet caps for retaining purposes. Similar in appearance to a pendant but better suited for retention.

Split Ring · Another term for "key ring".

Tensile · The breaking point of a chain.

XL Technology · A higher strength chain that adds additional pull strength without added weight. A Ball Chain Manufacturing exclusive.
