Multichannel surface raceways have multiple divisions for routing wire and cable. These raceways are used when different types of wire or cable need to be routed separately. Surface raceways mount on walls and ceilings to bring wire and cable into a space. Wire and cable are laid into or pulled through the raceways after installation, keeping the conductors from being exposed and preventing kinks. These raceways commonly house communication and power cable, and they're often installed in classrooms, offices, and hotels. Individual components in raceway systems must be purchased from the same brand and series to ensure compatibility.
