CABLE TRAY HANGERS Cable trays are structures used to hold and manage cables in buildings or industrial facilities. A cable tray hanger is a tool used to support and suspend cable trays. Typically, cable tray hangers are made to firmly fasten to walls, ceilings, or other structural components. To suit diverse cable tray types and installation needs, they are available in a range of sizes and shapes. In order to preserve the security and order of electrical and networking wires inside a building or facility, these hangers are essential to the stability and correct alignment of cable trays.
