I bought some round top euro screw cap roller balls on close out. They came with no instructions for assembly and WC web site doesn't have them. The product number is 128440. Anyways as you can see in the picture it hasa small spring. The center band and both couplers are threaded. It has a small (3/4") black cap I have no idea where it goes. There are no transmissions. I have no idea how to put these together. I always thought a pen was a pen, guessed wrong. Any help out there?
