Drag chains, also known as cable carriers or cable tracks, are mechanical devices used to protect and guide cables and hoses used in robotic and automated systems.

The plastic drag chain in the image is most likely a URBEST 18mm x 50mm Black Plastic Flexible Nested Semi Closed Drag Chain Cable Wire Carrier. It is a type of drag chain that is commonly used in electrical machines.

Drag chains protect cables and hoses from external sources of damage, such as debris or impact. They also help to ensure that the cables and hoses are neatly organized and properly routed. Drag chains are made of a high-strength plastic or metal material and are connected with hinges, allowing them to flex and bend easily. Drag chains are also equipped with end connectors that can be attached to the robot or machine frame.
