ABSTRACT:
A cable is moved through a cable fitting (for example, a BUB fitting) into a first opening of the fitting and out of a second opening of the fitting. A roller support structure is mounted on a fitting such that a set of rollers supported by the roller support structure is disposed inside the interior volume of the fitting. A spacer is disposed between the roller support structure and the fitting. An end of a cable is then moved into a first opening of the filling, over the rollers, and out of the fitting through the second opening. Once the cable has rolled over the rollers a desired distance though the fitting, the spacer is removed and the rollers are detached from the roller support structure. The rollers are slipped out around the cable and extracted from the interior volume. The roller support structure is then unmounted from the fitting.
