DOLUNTO 05B-1 Roller Chain Connector - 8mm Pitch, Carbon Steel, Industrial Transmission Link

Need to repair or extend a roller chain?

This DOLUNTO 05B-1 connector is a simple, solid solution.

It's designed for standard 05B-1 roller chain, which has an 8mm pitch (the distance between pins).

Made from durable carbon steel, it's built to handle the load in industrial machinery, conveyor systems, or heavy-duty bicycles.

Using a connector is often easier than using a master link or pressing pins – you just align the chain ends and snap this guy in place (usually with a chain tool).

Always double-check your chain's specifications (pitch, roller width) to ensure this is the right connector.

It's a small, inexpensive part that can get your equipment back up and running fast.

Keep a couple spares in your toolbox for quick repairs.
