A tray is a metal raceway for holding cable.
A tray, or cable tray, is a metal raceway used to support and hold cable as it runs through a building or facility. Typically built as a ladder, trough, or perforated structure, a cable tray provides an open, supportive pathway along which cables are laid and carried, distributing their weight and keeping them organized along the route. Cable trays are common in commercial and industrial facilities where many cables must be routed together.
Because the tray supports the cable along its run, the cable installed in it must be approved for tray use, and Type TC tray cable is specifically listed for this purpose. The open structure of a tray allows heat to dissipate and makes the cables accessible.
In commercial and industrial systems, cable trays carry power, control, and signal cable along defined routes. Recognizing the term helps in understanding how cable is supported and routed through a facility.

At Windy City Wire, the focus on quality cable connects to the systems that support it, including trays. Supplying tray-rated cable where required helps customers route power, control, and signal circuits dependably along the cable trays of commercial and industrial facilities.
