Morris Products 18057 Heat Shrink Wire Markers 3/4 in White

Product Description

The MORRIS PRODUCTS 18057 is a heat shrink wire marker cartridge designed for use with portable handheld thermal transfer labeling systems. The cartridge produces durable, shrink-fitted labels that conform tightly to wire and cable surfaces when heat is applied, creating a permanent, legible identification that resists abrasion, moisture, and mechanical stress. At 3/4 inches wide and finished in white, these markers are suited for clear, high-contrast printing on conductors of the appropriate gauge range. Electricians and low-voltage technicians use these cartridges as a fast, reliable method for cable and wire identification in panels, raceways, and junction boxes.

These heat shrink wire markers are used in residential, commercial, and industrial electrical installations where permanent wire identification is required. Typical applications include panel labeling, home-run identification, structured wiring, and any installation where code-compliant wire marking is part of the job scope. The cartridge format allows for on-site, on-demand printing directly from a compatible handheld thermal transfer labeling system, reducing pre-printed label inventory and speeding up field terminations.

Key Features

• Heat shrink material conforms tightly to wire or cable surface when heat is applied
• 3/4 inch width accommodates a range of conductor diameters
• White background provides high contrast for printed identification text
• Thermal transfer printing produces durable, smear-resistant labels
• Cartridge format designed for use with portable handheld labeling systems

Compatibility

Designed for use with portable handheld thermal transfer labeling systems that accept 3/4 inch heat shrink label cartridges.

Installation Notes

These markers are installed by licensed electricians or low-voltage technicians as part of a wire identification workflow. Apply labels to conductors before or after termination, then use an approved heat source to shrink the marker flush to the wire surface. Ensure the circuit or conductor is de-energized before handling. Follow applicable NEC requirements for wire marking and identification.
