ANSI Roller Chain Attachment Links
Add these links to your roller chain to attach brackets or guides, or to move materials directly. Use them for conveying, timing, and aligning. Do not use with Maintenance-Free ANSI Roller 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.
Tab links have holes on the tabs for mounting parts and hanging hooks. Pin links have extended pins for tripping switches.

Corrosion-Resistant ANSI Roller Chain Attachment Links
Made of treated steel, these links offer increased corrosion resistance over steel attachment links. Add them to your roller chain to attach brackets or guides, or to move materials directly. Use them for conveying, timing, and aligning. Holes on the tabs allow you to mount parts or hang hooks. 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. Do not use with Maintenance-Free ANSI Roller Chain.
Tab links have holes on the tabs for mounting parts and hanging hooks. Pin links have extended pins for tripping switches.

ANSI Attachment Chains
Attach brackets and guides to these chains—or move material directly—for use in conveying, timing, and aligning applications. Like roller chains, these attachment chains have solid rollers and bushings and a riveted construction for strength and durability. These factory-assembled chains save installation time and perform better than roller chains fitted with attachment links.
Chains with attachment tabs have holes for mounting parts and hanging hooks. Chains with attachment pins are good for tripping switches.
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.

ANSI Roller Chain and Links
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 join chain that requires an odd number of links. For trade number 35 and up, the side plate is easy to remove for attaching them to chain.
