Why choose it

These sleeves offer exceptional durability and clarity. The 3:1 shrink ratio ensures a tight, secure fit over a wide range of wire sizes, while the polyolefin material resists abrasion, chemicals, and UV exposure. The white colour provides high contrast for black thermal transfer printing, making legends easy to read even in low-light conditions. With UL and CSA approvals, they meet rigorous safety standards for industrial use.

Ideal use cases

• Marking wires and cables in control panels and switchgear
• Identifying conductors in industrial machinery and equipment
• Field installations requiring permanent, legible labels
• Applications subject to abrasion, oil, and harsh environments

Good to know

Compatible with a range of Brady thermal transfer printers, these sleeves are easy to integrate into existing workflows. The matte finish reduces glare, and the 160-sleeve cartridge minimises reloading downtime. RoHS compliance ensures environmental responsibility.
