A 21.0mm cassette looks far wider than the 4.2mm to 13.5mm conductor it suits, because the tube is supplied flattened and closes to a third of its diameter under heat. Ordering on the flat width alone is the most common mistake on this product, which is why we publish the cable range rather than leaving you to work it out at the bench.\u003c\/p\u003e\u003cp\u003eOnce printed and heated the tube grips the conductor without adhesive, so nothing lifts or unpeels in a warm switchboard, an engine bay or a rooftop DC run. Each cassette holds 1.5m of tube and is rated to UL 224 at 600V and 125 degrees Celsius, which is what makes it acceptable for permanent electrical identification rather than temporary marking.\u003c\/p\u003e\u003cp\u003eThis cassette fits the \u003ca href=\"\/products\/brother-pt-p750w-p-touch-machine-label-printer\"\u003eBrother PT-P750W\u003c\/a\u003e and the \u003ca href=\"\/products\/brother-pte560btvp-p-touch-machine\"\u003ePT-E560BTVP\u003c\/a\u003e, along with the PT-P700, PT-P900W and PT-P950NW.
