Examples include:Joining components that connect two tray sections togetherClamps or brackets used to fix trays to walls, ceilings, or other supportsCovers and cable retainers that secure cables and prevent movement SUP components are designed to restrain cables in a manner that can withstand forces generated during normal operation or short circuits, ensuring the integrity and safety of the electrical installation . They are integral to creating a complete cable support system, which may also include main tray lengths, fittings, and support elements like wall brackets or suspended supports . Understanding SUP components is important for engineers and installers because they ensure that the cable tray system functions correctly, maintains cable organization, and meets safety standards in industrial, commercial, or residential environments.
