Brady PermaSleeve Heat-Shrink Sleeves (M21-250-C-342) - Black On White Sleeves

The Brady B342 Thermal Transfer / Dot Matrix Printable Nylon Cloth Label is a high-performance, non-adhesive, heat shrinkable wire marking sleeve designed to provide both insulation protection and permanent identification for wires and cables. Made from irradiated polyolefin, these 3:1 shrink ratio sleeves offer excellent durability, resistance to abrasion, chemicals, and extreme temperatures. The full-circle design ensures a secure, permanent fit around wires, while clear, legible text can be printed using a Brady printer. Ideal for environments with temperature fluctuations, B342 markers are fade-resistant, fire-retardant, and UL recognized, making them a reliable choice for wire identification in industrial and electrical applications.
