A ladder-type cable tray system comprising a first cable tray section and a second cable tray section. Each cable tray section includes first and second rails extending lengthwise of the section at opposite sides of the section and a plurality of rungs extending between the rails at intervals spaced lengthwise of the section. Each of the first and second rails has a tubular portion forming a hollow beam extending the length of the rail. The tubular portion has open ends at opposite ends of the rail and a rung-supporting portion integrally formed as one piece with the tubular portion and depending therefrom. The system further comprises fasteners for securing the rungs to the rung-supporting portions of the first and second rails in a position wherein the rungs span the rung-supporting portions, and a plurality of splices for connecting the first and second cable tray sections end to end. The splices include a first splice sized and shaped for a snug telescoping fit within adjacent open ends of the tubular portions of the first rails of the two cable tray sections, and a second splice sized and shaped for a snug telescoping fit within adjacent open ends of the tubular portions of the second rails of the two cable tray sections.
