Dymo - DYM18051 White heat shrink tube offers a premium method of labeling wires and cables. Simply slide the tube onto the cable and shrink snugly to the cable using a heat gun. Labels will never fall off. The cassette fits into all Dymo Rhino printers including 6500, 6000, 5200, 5000 and 3000. Industrial-grade polyolefin offers a 3:1 heat shrink ratio and the convenience of printing directly on the 1/4" (6mm) tubing itself, eliminating the need for an extra labeling step.
