The cable trays used for structured cabling are called cable ducts
Cable ducts, also known as cable trays or trunking, are enclosed channels designed to house and protect electrical cables. They come in various materials (PVC, metal, fiberglass) and configurations (surface-mounted, underground, etc. ) to suit diverse applications. While the choice largely depends on the environment and volume of cabling, the most commonly used systems fall into three main categories: cable trays, cable trunking, and conduits. Each offers unique advantages in terms of accessibility, protection, and flexibility. They have openness, and therefore, everything is easily seen. People worry about which system is safer, more cost-effective, and easier to install.
