3M 7100138240 Diamond Grade Conspicuity Marking Red 2x12 in

Product Description

The 3M 7100138240 is a pre-cut microprismatic reflective conspicuity marking strip designed for visibility compliance on large commercial vehicles. The 983-72 ES sheeting uses a pressure-sensitive adhesive backing that bonds directly to trailer body panels, mud flap brackets, and other flat or slightly curved surfaces. Each strip measures 2 inches wide by 12 inches long and delivers high-intensity retroreflection to meet federal conspicuity marking requirements. The red colorway is used in alternating red-and-white patterns per FMCSA standards. Strips are cut to length at the factory, eliminating field trimming on most standard applications. The package contains 100 strips and weighs 2 pounds.

This product is used in commercial trucking and fleet maintenance applications where DOT conspicuity tape is required on trailers, semi-trucks, and other large vehicles. It is typically applied during new vehicle outfitting or as a replacement when existing tape is faded, peeling, or damaged. Fleet maintenance shops, body shops, and owner-operators handling their own DOT compliance work are the primary installers. The 2-inch by 12-inch format suits standard conspicuity band layouts on trailer rear and side panels.

Key Features

• Microprismatic sheeting provides high-intensity retroreflection for nighttime and low-visibility conditions

Compatibility

Designed for application to trucks, trailers, and large commercial vehicles requiring DOT conspicuity marking coverage on flat or moderately curved exterior surfaces.

Installation Notes

Surface preparation is critical for adhesive bond strength — clean and degrease the mounting surface thoroughly before application. Apply at temperatures within the adhesive manufacturer's recommended range and press firmly across the full strip length to eliminate air pockets. No special tools are required beyond a roller or squeegee for seating the adhesive. Verify final placement meets FMCSA conspicuity marking location requirements before returning the vehicle to service.
