Ideally suited to mark cables, fiber cables, and wires, this 11.2mm (0.44in) black print on white shrink wrap label tubing is recommended for diameters ranging from 2.1mm to 7mm (0.082in to 0.27in). 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 600 volts and 257° F (125° C). 1.5m (4.9ft) of tube per cassette. 1 cassette per package. For use with P-touch PT-E300, PT-E300M, PT-E500, PT-E550W, PT-E800W and P-touch Desktop 900 series Label Printers.
