Ideally suited to mark cables, fiber cables and wires, this 21 mm (0.82") yellow print on white shrink wrap label tubing is recommended for diameters ranging from 4.2 mm to 13.5 mm (0.16" to 0.53"). With a 3:1 shrink ratio, this tubing can shrink to a third of its size when heat is applied, enabling it to pass over connectors and still shrink down to a snug fit on the cable. Meets UL 224 standard and can withstand up to 600V and 257° F (125° C). 1.5 m (4.9') of tube per cassette. 1 cassette per package. For use with P-touch 500 Series, 800 Series and 900 Series label printers.
