3M 7100139512 Diamond Grade Conspicuity Marking Roll

Product Description

The 3M 7100139512 is a Diamond Grade Conspicuity Marking Roll (Series 983-32) designed to increase the visibility of trucks, trailers, and other large commercial vehicles. The roll features alternating 11-inch red and 7-inch white segments of microprismatic reflective sheeting that significantly extends detection distance for oncoming drivers under low-light and nighttime conditions. A pressure-sensitive adhesive backing allows direct application to flat or curved vehicle surfaces without additional adhesives or special tools. Fleet operators, body shop technicians, and DOT compliance crews are the primary installers of this product.

This conspicuity tape is intended for application on the sides and rear of heavy trucks, semi-trailers, flatbeds, and other large vehicles where retroreflective marking is required for regulatory compliance. The alternating red and white pattern meets the color and segment-length requirements commonly referenced in federal and state vehicle conspicuity standards. It is well suited for fleets undergoing DOT compliance upgrades and for OEM trailer manufacturers integrating conspicuity marking into new builds.

Key Features

• Microprismatic sheeting construction delivers high retroreflectivity for extended detection distance at night

Installation Notes

Installation is typically performed by fleet maintenance technicians, body shop crews, or DOT compliance specialists. Clean and degrease the application surface thoroughly before installing the tape to ensure proper adhesion. Apply firm pressure along the full length of the tape using a roller or squeegee to seat the adhesive. Allow adequate cure time before exposing the tape to water or high-pressure washing.
