3M 7010388939 Diamond Grade Conspicuity Marking 983-326

Product Description

The 3M 7010388939 is a Diamond Grade Conspicuity Marking tape, also referenced as 983-326 ES, designed for high-visibility safety marking on commercial trucks, trailers, and large vehicles. The sheeting uses a prismatic retroreflective construction metallized with a pressure-sensitive adhesive backing, allowing it to return light directly toward the source across a wide range of angles. A clear poly liner protects the adhesive until application. This product is sold by the roll and is used by fleet maintenance technicians, body shops, and DOT compliance crews who need to meet federal conspicuity requirements.

This marking tape is applied to the rear and sides of trucks, trailers, and other large vehicles to improve detection distance for approaching drivers, particularly in low-light and nighttime conditions. The red and white alternating color pattern is the standard configuration required under FMCSA conspicuity regulations for most commercial trailers. It is well suited for new trailer builds and refurbishment of existing fleets where worn or missing reflective tape must be replaced to maintain compliance.

Key Features

• Prismatic retroreflective sheeting for maximum light return and detection distance
• Metallized construction enhances reflective performance compared to standard engineering-grade tape
• Pressure-sensitive adhesive backing for direct application without additional adhesive or primers
• Clear poly liner protects adhesive until ready to install
• Red and white color pattern meets standard FMCSA conspicuity requirements for commercial trailers
• Sold by the roll for efficient coverage of truck and trailer perimeters

Compatibility

Designed for application to trucks, trailers, and large vehicles requiring DOT-compliant retroreflective conspicuity marking.

Installation Notes

Surface preparation is critical before applying pressure-sensitive reflective tape. Clean the mounting surface thoroughly to remove dirt, oil, and loose coatings before removing the poly liner. Apply firm, even pressure along the full length of the tape to ensure proper adhesion. No special tools are required, but a roller or squeegee helps eliminate air pockets and improves bond strength.
