Abstract: A device for carrying a rail car coupling knuckle. The device includes an open end, a closed end and a retaining pin for securing the open and closed ends together. The open end includes a pair of substantially parallel tubes that are fixedly attached to a metal plate. Preferably, the tubes have substantially equal inner diameters. One of the tubes has a flange near one end and an opening near the other end. The closed end includes a pipe and a tube that are fixedly attached to a metal plate. Preferably the pipe and the tube of the closed end is substantially parallel to each other so as to be in alignment with the tubes of the open end. The outer diameter of the pipe of the closed end is slightly smaller than the inner diameter of the tube of the open end. Likewise, the outer diameter of the other tube of the open end is slightly smaller than the inner diameter of the tube of the closed end.
