Self-adhesive vinyl printer labels Brady M4-91-427-YL — 2.54×3.81 cm, black on yellow, 180 labels

Brady M4-91-427-YL are self-adhesive vinyl printer labels measuring 2.54 × 3.81 cm, printed black on a yellow background and supplied on a roll of 180 labels. Designed for thermal-transfer and compatible label printers, these labels include a clear self-laminating overlaminate that protects printed text against abrasion, solvents, oil, grease and weather. The vinyl material and permanent acrylic adhesive make the labels suitable for marking cables, wires, assets and safety information in industrial and office environments.

Advantages

The label material is flexible for application on tightly curved surfaces and wires, and the permanent acrylic adhesive bonds reliably to smooth, rough, powder-coated and irregular surfaces. A clear, non-printable overlaminate increases durability and protection of printed information, while the vinyl substrate is self-extinguishing and resistant to common workplace chemicals and environmental stress. These characteristics support long-term legibility and reduced relabeling needs.

How to use

Load the roll into a compatible thermal-transfer or portable Brady label printer according to the printer manual. Select appropriate print settings for vinyl and thermal-transfer ribbon to ensure high-contrast black printing. After printing, apply the label to a clean, dry surface and press firmly to ensure full adhesive contact. For cable and wire marking, route the clear self-laminating tail over the printed area when applicable to provide additional mechanical protection.

Usage recommendations

For best adhesion, clean surfaces of oil, dust and loose particles with a compatible cleaner and allow to dry before application. Use thermal-transfer ribbons recommended for vinyl materials to maximize print durability. Store labels in a cool, dry place away from direct sunlight and extreme temperatures to preserve adhesive performance and material stability.
