The 3M 7010389826 is a Diamond Grade retroreflective safety sign letter and number set designed for the production of safety and emergency exit signage. The retroreflective sheeting construction delivers high-visibility characters that return light to the source, making signs readable in low-light and nighttime conditions. At 6 inches by 2 inches per character, these letters and numbers are sized for standard safety sign applications. Installation is handled by facility maintenance crews, safety coordinators, and sign fabricators working in industrial, commercial, and institutional environments.
This product is used wherever high-visibility, durable safety signage is required. Typical applications include danger warnings, emergency exit identification, and directional safety markers in warehouses, manufacturing facilities, and public buildings. The retroreflective Diamond Grade construction meets demanding visibility requirements for both interior and exterior signage programs.
Designed as an OEM-style retroreflective letter and number set compatible with standard safety sign fabrication systems requiring Diamond Grade sheeting material.
Application is typically performed by sign fabricators or facility safety personnel following applicable OSHA signage placement requirements. Clean and dry the substrate surface before applying retroreflective characters to ensure full adhesion. Do not apply over damaged, wet, or contaminated surfaces. Power down or de-energize any adjacent electrical equipment as required by site safety protocols before working in the sign installation area.
