A cable support apparatus includes first and second horizontal supports spaced-apart and substantially parallel to one another, a plurality of vertical supports spaced-apart horizontally along the first and second horizontal supports, and at least one junction box assembly configured to hang from the first horizontal support. Each horizontal support is formed from wire stock. Each vertical support is formed from wire stock and secured to each of the first and second horizontal supports. At least two of the vertical supports include cable-receiving segments that cooperate to define at least one cable-receiving channel extending horizontally. The at least one junction box assembly includes an input and an output for receiving cable ends of cables disposed within one of the at least one cable-receiving channels to enable joining of the cable ends within the junction box assembly.
