Brother Black on White Heat Shrink Tube designed for marking and identifying cables, fibres, and wires. This 21mm tape cassette features a 3:1 shrink ratio and is 1.5m long, shrinking when heated to facilitate easy cable identification. It is recommended for use with cables between 7.3mm to 14.3mm, ensuring a durable and easily readable result. Brother P-touch Tapes are constructed with tough, professional-grade materials and adhesives, built to meet the demands of tradespeople and professionals seeking reliable, long-term identification that endures. This non-adhesive tape is made from a special material supplied in a flat tube format within the cassette. Once printed with the necessary identification details, the tube is opened and placed over a cable or connector. Upon heating with a heat gun, the tube shrinks to approximately half its original width, securely gripping the cable without the need for adhesive, thus preventing peeling even in warm conditions. TZe tape cassettes are user-friendly and quick to install, available in a variety of label widths, colours, and materials, providing crisp, sharp, and legible labels for any task. Applications include Electrical Wires and Cables. Compatible with the following Brother Label Machines: PT-E300VP, PT-E550WSP, PT-E550WVP, PT-E550WVPNI, PT-D800W, PT-P900W, PT-P950NW.
