Brady M21 Vinyl Label Roll 0.5" x 21' — Black on Gray

Brady Authentic M21-500-595-GY is a rugged, all‑weather vinyl identification label roll (0.5" wide × 21' long) printed black on gray and built for indoor and outdoor equipment, lab, and ID applications.

Engineered and tested by Brady material scientists, this vinyl label stock combines strong adhesion, chemical resistance and extended outdoor life so you can create durable, readable labels for cables, instruments, panels and curved or rough surfaces. It is formulated to work with Brady M210/M211 and BMP21 series handheld printers and is rated to withstand a wide temperature range and common industrial contaminants.

How durable is this label outdoors and in tough industrial settings?

The M21 vinyl material is designed for long-term outdoor exposure and heavy-duty indoor use without rapid fading or lifting. Brady’s in‑house testing targets sun, temperature extremes and exposure to oils and many chemicals to ensure reliable performance.

• Typical outdoor life: 8–10 years under normal conditions
• Operating temperature range: −40°F to 180°F (−40°C to 82°C)
• Resists grease, oil and most industrial chemicals
• Adheres to irregular, rough and curved surfaces

Which printers and projects is this label compatible with?

This roll is sized and formatted specifically for Brady handheld label makers in the M21/BMP21 family, making it a straightforward choice for on-the-spot labeling and routine maintenance tasks. Printers are sold separately.

• Compatible with: M210, M210‑LAB, M211, BMP21‑PLUS and BMP21‑LAB models
• Label width: 0.5" (12.7 mm); roll length: 21' (6.4 m)
• Pre‑terminated core/roll dimensions match Brady media bays for quick loading
• Black print on gray substrate for high contrast and legibility

Can these labels handle curved surfaces and cable identification?

The vinyl backing and adhesive system are optimized to conform and stick to small radii, textured panels and common cable sheaths without peeling. That makes this roll a good choice for marking wires, hoses, valves and instruments where smoothed, permanent adhesion is needed.

• Flexible vinyl conforms to curved and irregular shapes
• Adhesive sticks to a range of surfaces including plastics and painted metal
• Durable print contrast keeps information legible over time
• Ideal for serial numbers, barcodes, safety IDs and asset tags
