The 3m Tape Measure Class 2 by BMI is designed to withstand tough work environments. It features a rust-protected, phosphate ground coating with an extra-durable transparent layer that lasts 10 times longer than standard non-abrasive coatings. The return lock spring, made from special spring steel, ensures a long service life, while smooth operation is maintained by inserted winding coils or distance washers. Encased in a high-impact ABS or polyamide case, this tape measure is both durable and reliable. With mm-graduation, EEC pattern approval, and suitability for calibration, it meets EC Class II accuracy standards, offering precision of 2 m ± 0.7 mm, 3 m ± 0.9 mm, and 5 m ± 1.3 mm.
