Dymo Rhino 18055 White Heat Shrink Tube 1/2" (12mm) are ideal for anyone looking for a superior method for labeling cables. Rhino heat shrink tubes are a more permanent labeling solution, as the tubes actually slide over the cable and are shrunk to the size of the cable using a heat gun. Unlike other labeling methods, you can save time with these tubes, as you print directly onto the heat shrink tube and then shrink it into place. The white heat shrink tubes provide a sharp contrast against any black text printed on them, and are ideal for use by anyone working with security systems, audio and video system installation, as well as many other industries.
