3M 7100033931 Electrical Tape 2in Translucent Series 40 72yd

Product Description

The 3M 7100033931 is a translucent acrylic-adhesive electrical tape designed for insulation, bundling, and protective wrapping applications in electrical systems. At 1 mil thick and 2 inches wide, this tape delivers a clean, conformable wrap suited to wire harnessing, connector protection, and general electrical insulation tasks. Each roll provides 72 yards of usable length, making it well suited for high-volume or continuous runs. The acrylic adhesive system maintains reliable bond strength across a wide temperature range, rated from 130 degrees C minimum operating temperature up to 266 degrees F maximum operating temperature. Licensed electricians, industrial maintenance techs, and panel builders are the primary installers.

This tape is appropriate for residential, commercial, and light industrial electrical work where a translucent, low-profile tape is preferred. The 2-inch width accommodates larger conductors, multi-conductor bundles, and wrap-and-overlap insulation tasks without multiple overlapping passes. Series 40 designation places it within 3M's utility-grade electrical tape lineup, suitable for general-purpose insulation and harnessing work where a clear or translucent finish is functionally or visually required.

Key Features

• Translucent finish allows visual inspection of underlying conductors or markings after application
• Acrylic adhesive provides long-term bond stability across wide operating temperature ranges
• 2 inches wide covers larger conductors and bundles efficiently with fewer passes
• 72-yard roll length reduces roll changes on high-volume jobs
• 1 mil thickness delivers conformability for irregular or contoured wrap applications
• Maximum operating temperature of 266 degrees F suits most standard electrical insulation environments

Compatibility

Designed as a general-purpose electrical insulation and harnessing tape compatible with standard copper and aluminum conductors in low-voltage electrical applications. No specific model or system compatibility data was provided in the product input.

Installation Notes

Installation is typically performed by licensed electricians or qualified maintenance technicians in accordance with NEC guidelines for insulation and conductor protection. Power down and lock out the circuit before applying tape to any energized conductor or termination point. Apply with consistent tension to avoid air pockets or lifting at the tape edge. Do not stretch the tape beyond its conformable limit, as this may reduce adhesive contact and long-term bond integrity.
