  • Wire cable tray
    Patent number: 6138961
    Abstract: A cable tray is formed by a trellis of wires including longitudinal wires and transverse wires, the combination forming a trough with a bottom and sides. At least one of the longitudinal wires other than the edge longitudinal wires of the sides has a cross-section different than that of the other wires, in practice a diameter less than that of the other wires. This reduces the weight of a wire cable tray without reducing its mechanical strength.
