Brother TZe-SL251 is self-laminating label tape for P-touch label makers, intended for clear cable marking. It prints black text on a white background, and the laminate covers the printed area to protect the marking.
The tape is 24 mm wide and 8 m long, with a printable height of 9.5 mm. Brother notes that this format is suitable for marking larger-diameter CAT6A cables.
Brother lists it for P-touch EDGE industrial labeling tools, including PTE500, PTE550W, PTE800W, PTP750WVP, PTP900, PTP900W and PTP950NW.
