Cable management refers to the installation of equipment to secure cable for electrical services in a building.The term is used for products or workmanship. Cable management is important in(IT), communications, and power distribution.

Cable management both supports and contains cables during installation, and makes subsequent maintenance or changes to the cable system easier. Products such as cable trays,cable ladders, and cable baskets are used to support a cable through cabling routes.

The IT industry needs data cables to be added, moved, or removed many times during the life of the installation. It is usual practice to install "fixed cables" between cabling closets or cabinets. These cables are contained in cable trays etc., and are terminated at each end onto patch panels in the communications cabinet or outlets at the desktop. The circuits are then interconnected to the final destination using patch cords.
