In the electrical wiring of buildings, a cable tray ystem is used to support insulated electric cables used for power distribution and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction. They are especially useful in situations where changes to a wiring system are anticipated, since new cables can be installed by laying them in the tray, instead of pulling them through a pipe. The standard length is 2.4mtrs long. There are many sizes of width cable tray available. Check out our range today.
