Brady M21-500-595-BK Vinyl Labels 0.5" x 21' White on Black

Brady Authentic M21-500-595-BK is a 0.5"-wide, 21-foot roll of white-on-black all-weather vinyl labels engineered for long-lasting indoor and outdoor identification with M21/M210 series printers.

These vinyl labels are formulated by Brady’s in-house materials scientists to deliver high adhesion to irregular and curved surfaces, resistance to grease and many industrial chemicals, and reliable performance across extreme temperatures. Designed specifically for use with M210, M210-LAB, M211, BMP21-PLUS and BMP21-LAB label printers, the M21-500-595-BK roll provides a compact, easy-to-load solution for equipment, lab, utility, and general ID tasks.

How durable are these labels outdoors and in harsh environments?

The vinyl substrate and adhesive system are built to last: Brady reports typical outdoor durability of 8–10 years and an operating temperature range from -40°C to 82°C (-40°F to 180°F). Labels resist common industrial challenges such as grease, oil, and many chemicals, and the material is formulated to remain legible when mounted on rough or curved surfaces.

• Average outdoor durability: 8–10 years

What applications are these labels best suited for?

These labels are versatile across a broad set of identification tasks where durability and legibility matter. Use them for asset tags, lab samples, cable and pipe marking, outdoor signage, and industrial equipment labels where exposure to weather, oils, and temperature extremes is expected.

• Asset and equipment identification in industrial settings
• Laboratory labeling for containers and racks
• Cable, conduit, and pipe marking with curved-surface adhesion
• Outdoor signs and tags requiring long-term UV/weather resistance

How should I store and handle the label rolls for best results?

Store unopened rolls in a cool, dry place away from direct sunlight to preserve adhesive performance and print quality. When loading, ensure the printer path is clear and print settings match the 0.5" width for accurate positioning and optimal contrast.

• Storage: cool, dry, out of direct sunlight
• Load with the vinyl facing the print head per device instructions
• Set printer width to 0.5" for correct layout
• Test a sample label to confirm adhesion and legibility before bulk printing
