About Roller Chain and Sprockets

Double-Pitch ANSI Attachment Chains
Attach brackets and guides to these chains—or move material directly—for use in conveying, timing, and aligning applications. With links that are twice as long as standard attachment chain links, these lightweight chains are designed for long drives and low- to moderate-speed applications. Use with standard sprockets with at least 24 teeth. 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. The attachment tabs have holes for mounting parts and hanging hooks.
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.
