A support structure is provided for supporting a cable. The support structure includes a body portion extending circumferentially about an axis. The body portion includes a first wall, a second wall extending substantially parallel to the first wall, and a third wall coupled between the first wall and the second wall. The first wall, the second wall, and the third wall define an opening extending along a circumferential length of the body portion. The body portion receives the cable within the opening. A retention structure is coupled to the first wall and projects from the first wall towards the second wall. The retention structure extends substantially parallel to the third wall. The retention structure retains the cable within the opening.
