Straight sections of metal ladder cable trays are designed for routing of wires and cables using straight cable ways. In addition, cable trays may be completed with covers (KL) and shaped sections (cable way turns, drops and rises). To secure cable trays, cable rack arms and complete cable racks are used. It is recommended to use hot-dip galvanized cable trays for outdoor cable support system operation, cable trays made of steel galvanized using Sendzimir process for indoor operation, and stainless steel cable trays for operation in highly corrosive environments.
