Brady B-427 Self-Laminating Vinyl Wire Marker Labels, White/Translucent, 38.1mm x 38.1mm, 240 Labels/Roll, for BMP41/BMP51/BMP53/M511

For cable and wire identification that must survive abrasion, oil, and weather, the Brady B-427 self-laminating vinyl label offers a print-on area plus a clear overlaminate tail that wraps around to shield the printed text. Unlike standard labels that smudge or peel on curved surfaces, this roll is engineered specifically for wire marking on 10–4 AWG conductors, with a permanent acrylic adhesive that bonds to rough jackets and a temperature range from -40°C to 70°C. The 38.1 mm × 38.1 mm total label size gives enough overlaminate to fully encircle the wire, while the 9.53 mm print-on height keeps legends crisp and legible. Each roll contains 240 labels on a 25.4 mm core, compatible with Brady BMP41, BMP51, BMP53, M210, M210-LAB, M211, M611, and M710 printers (adapter required for M710), so you can print exactly what you need on demand.

Highlights

• Self-laminating design: translucent vinyl overlaminate wraps over the printed area to protect text from smearing, chemicals, and abrasion.
• Permanent acrylic adhesive sticks to wires, cables, and curved surfaces without lifting, even in oily or damp environments.
• Optimised for 10–4 AWG wire (4.01–5.21 mm diameter) — ideal for industrial control panels, network cabinets, and electrical installations.
• UL Recognized and CSA Accepted, RoHS compliant, and resistant to water, oil, and common solvents.
• 240 labels per roll, 38.1 mm × 38.1 mm total size, with a 9.53 mm print-on area height for clear, scannable legends.

In daily use

These labels are a reliable choice for electricians and panel builders who need durable wire identification. Print a batch on your Brady printer, peel, and wrap: the clear tail laminates the printed area, locking the legend under a protective layer. The adhesive holds on textured insulation and curved cables, and the labels stay legible through washdowns, oil exposure, and temperature swings. The roll format keeps your workstation tidy and reduces waste, while the 240-label count supports high-volume projects without frequent reloading.
