BRADY BMP51/BMP53/M511 PermaSleeve Heat-Shrink Label Cassette, Black on White, 12.7mm x 2.13m, 16-10 AWG

For labelling wires and cables that must endure tough industrial conditions, the Brady M5-31-7425 cassette stands apart from ordinary label rolls. Instead of a separate sleeve and printer ribbon, this PermaSleeve B-427 cartridge combines both in a single drop-in unit for BMP51, BMP53, and M511 printers. The result is crisp, permanent identification without the mess or downtime of ribbon changes.

Highlights

• Heat-shrink polyolefin sleeve with a 3:1 shrink ratio grips tightly around wires from 16 to 10 AWG.
• Thermal transfer printing delivers sharp black text on a white background that stays legible for years.
• Resists abrasion, chemicals, corrosion, humidity, UV light, and weather, making it suitable for outdoor and harsh environments.
• Flattened label width of 12.7 mm (0.5") and a roll length of 2.13 m (7 ft) provide ample material for repeated jobs.
• UL recognized and CSA accepted, with RoHS compliance for global use.

In daily use

Technicians can quickly identify control panel wiring, network cables, or power leads without guesswork. The sleeve slides over the wire before termination, then shrinks to a snug fit after heating, so the label cannot peel, smear, or fall off. The matte white surface reduces glare, and the high-contrast print remains readable even in low light or after exposure to oils and solvents.
