The Brady M4-91-427 is a premium self-laminating vinyl wrap-around label cartridge designed specifically for 10 to 4 AWG wires, making it highly effective for identifying CAT6, 4-pair UTP copper, fiber optic, and coaxial cables. Utilizing Brady's B-427 thermal transfer printable translucent vinyl, these labels feature a white printable zone (1.0" W x 0.50" H) alongside a clear tail that wraps around the cable to over-laminate and protect the printed text. This structural design ensures outstanding legibility and robust protection against abrasion, solvents, oil, grease, weather, and extreme temperatures.
Equipped with a permanent acrylic adhesive, the labels adhere securely to smooth, rough, highly curved, powder-coated, and irregular surfaces. Engineered for demanding indoor and outdoor environments, this cartridge contains 180 pre-sized thermal transfer labels providing a matte finish. It is fully compatible with Brady BMP41, BMP51, and M511 portable label printers.
