The M21-375-595-BK is a B-595 series continuous vinyl label cartridge. This cartridge contains a single roll of white-on-black vinyl tape that measures 0.375 inches (9.53 mm) in width and 21 feet (6.40 m) in length. The B-595 material is highly pliable with an aggressive adhesive, allowing it to conform to irregular, rough, and curved surfaces while offering an average outdoor durability of 8-10 years. Resistant to grease, oil, dirt, and most industrial chemicals, it is ideal for labeling components, equipment markings, and production area identification.
