Brady PermaSleeve M6-375-175-342-BL is a blue heat-shrink sleeve label for identifying wires and cables. Its printable surface lets you add a clear marker, while the sleeve fits around the conductor when heat is applied.
Made from B-342 heat-shrink polyolefin, it has a 3:1 shrink ratio. The sleeve measures 0.375 in in diameter by 1.75 in wide and is supplied as a roll of 100. Its listed wire gauge range is 12 AWG to 4 AWG.
The label is single-side printable by thermal transfer. It is compatible with BMP61, M610 and M611 printers, plus BMP71 and M710 models used with a media adapter. A separate ribbon is required; ribbon choice depends on the printer.
