3M 888519021972 Dot Conspicuity Tape White 4in X 15ft

Product Description

The 3M 888519021972 is a white DOT conspicuity tape made from reflective sheeting material, designed to meet federal visibility requirements for commercial vehicles and trailers. This tape measures 4 inches wide by 15 feet long (180 inches total), providing enough coverage for a full trailer side or multiple shorter runs. The reflective sheeting construction bounces light back toward the source, improving vehicle visibility at night and in low-light conditions. Fleet maintenance technicians and DOT compliance specialists are the primary installers of this product.

This tape is used on the sides and rear of trailers, flatbeds, box trucks, and other commercial vehicles that require DOT-compliant retroreflective marking. It is well suited for new trailer builds, periodic compliance re-striping, and replacement of worn or damaged sections. The white color is typically applied to trailer sides in alternating patterns per FMCSA requirements. One roll covers a 15-foot run without a seam.
