Cable tray ducts or trucking, also known as cable raceways, are essential components in electrical installations, providing a safe and organized way to route and protect cables. They come in various types, including ladder cable trays, solid bottom trays, wire mesh trays, and channel trays, each designed to meet specific cable management needs. These trays are typically made from materials such as steel, aluminum, stainless steel, or fiberglass, offering different levels of strength, durability, and corrosion resistance.
