Cable Tray is a support system used to securely organize and route electrical cables and wires in a building or facility. Cable trays are typically made of metal or plastic and are designed to provide a safe and organized way to distribute cables and wires throughout a space. These come in various sizes and configurations, including ladder, solid-bottom, and ventilated types. Ladder-style cable trays have a series of parallel rungs or rails that support the cables and wires, while solid-bottom cable trays have a solid base that can be perforated for ventilation.
