This 23.6mm black on white HSe-251 tape cassette has been designed specifically for the marking and identifying of cables, fibre and wires with an outside diameter of 7.3mm-14.3mm.When the printed tube is placed over a cable and heated with a heat gun, the tube shrinks down, gripping the cable tightly. No adhesive is needed, ensuring that even in warm environments the heat shrink tube will not unpeel from the cable.Compatible with a range of our P-touch printers, this genuine Brother HSe-251 tape is an essential part of any electrician’s toolkit and offers clear labelling that helps you meet safety requirements and do your job more efficiently.
