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.
For technical drawings and 3-D models, click on a part number.
