Rack-A-Tiers 52491 Acrylic Tip Valve-Activated U-Phase Wire Marker, 5-Inch

Rack-A-Tiers 52491 Acrylic Tip Valve-Activated U-Phase Wire Marker, 5-Inch

The Rack-A-Tiers 52491 is a 5-Inch acrylic tip, valve-activated U-Phase wire marker designed to give electricians and installers a fast, reliable way to identify and color-code conductors during rough-in, service work, and panel terminations. Each marker features a durable acrylic tip that is engaged with a simple valve-activated action, allowing technicians to apply crisp, legible phase markings directly onto wire and cable without the mess or slow application time associated with traditional paint pens or adhesive tape wraps. The 52491 is available with White, Blue, Red, and Green markings, giving crews the color options needed to follow common U-Phase and utility color-coding conventions on the job site.

Key Features

• 5-Inch Size: Compact 5-Inch marker sized for convenient handheld use in panels, junction boxes, and along conductor runs.
• Acrylic Tip Construction: A durable acrylic tip delivers consistent, controlled marking without smearing or excess buildup, helping crews maintain clean, professional-looking phase identification.
• Valve-Activated Application: The valve-activated tip dispenses marking fluid on demand, reducing waste and allowing quick, repeated use throughout a shift without drying out between applications.
• U-Phase Color Coding: Offered in White, Blue, Red, and Green to support standard U-Phase and utility color identification schemes used to distinguish circuit phases and neutral conductors.
• Job-Site Ready: Sized and built for use directly from a tool pouch or bag, making it easy for electricians to keep phase markers on hand during rough-in and finish work.
• Fast Identification: Speeds up conductor identification compared to writing labels by hand, helping crews stay organized on multi-circuit installations and panel work.
