High-Strength Corrosion-Resistant ANSI Roller Chain and Links
Treated steel chain has over eight times the capacity of stainless steel chain.
Connecting links are also known as master links. They're used to join the ends of a chain length. The side plate is easy to remove for attaching to a chain. Adding links are also known as roller links. They require two connecting links to join chain. Adding-and-connecting links are also known as half links and offset links. A combination of connecting and adding links, they can join chain that requires an odd number of links. The side plate is easy to remove for attaching to chain.
