It is a rod that assembles in 3 pieces, tow 12" and one 6". So I guess you have choose to use only 1, 2 or three rods giving you 3 lengths to choose from. The rods are about a half inch in diameter and are chrome like the fixture. Each rood is threaded so each screws securely into the other. The rod will screw into the light fixture at the lower end and into a bracket at the light box.
We have not installed yet, just opened the box to view. So I may not be the best reply you get, but it is not rocket science and the assembly seems as I have noted. But not a chain.
