These labels allow cables and wires to be easily marked for grouping. Designs with a labelling block can be lettered by hand or with a laser printer. Depending upon the material, they allow permanent labelling for indoor or outdoor use. A special variant of the cable tag has colour identification. It is easy to use: It is wrapped around the cable and stuck together. Cable tags are used not only in the switch cabinet, but for any application in which clear cable labelling facilitates day-to-day work.
