Brady M7-21-427 self-laminating vinyl labels are made for identifying wires and cables. Each wrap-around label combines a printable area with a translucent overlaminating section that folds over the text, helping protect it from everyday contact.
The labels use a permanent acrylic adhesive with water and oil resistance. The B-427 material has a stated service temperature range of −40°C to 70°C, supporting identification work across the conditions covered by that range.
This material is listed for Brady M7 printers, including the M710 and BMP71. It provides a purpose-made format for printing and applying cable identification labels.
