Red Phase Discs

Our Red Phase Discs provide a clear, durable way to identify electrical phases, helping engineers, contractors, and maintenance staff work safely and efficiently. They are widely used in construction projects, facilities management, and MRO operations where accurate phase marking is essential.

We supply these discs on sheets, which keeps them organised and easy to transport between sites. This format also allows for quick selection and application, helping maintain a smooth workflow during installations or maintenance tasks.

Constructed from self-adhesive vinyl with a permanent adhesive, these discs stick firmly to clean, dry surfaces. The bright red colour offers excellent visibility, reducing the risk of wiring errors and improving safety in busy work environments.

Available sizes:

• 10mm diameter

• 15mm diameter

• 20mm diameter

Common uses include:

• Phase identification in electrical wiring

• Colour-coding in switchgear and control panels

• Compliance with wiring and safety standards

• Long-term labelling in industrial or commercial settings

We offer fast delivery and bulk order discounts, making it easy to keep your marking supplies fully stocked for every project.
