What are master links used for? A master link is a chain accessory that provides convenient connection and disconnection of a chain without the need of a chain tool. In lifting, a master link is used when making sling assemblies and any number of rigging connections. What are the two types of master links? The most commonly used types of links and rings are: Oblong master links. Master link sub-assemblies. Pear-shaped links. There are two kinds of master links. The first kind is a straight-chain line-compatible link, often seen on single-speed and hub-geared bikes. The other is a derailleur-compatible external link.
