Trusted by professional users for decades, the innovative STANLEY® Micro PowerLock® slide lock mechanism was one of the first of its kind when launched in 1969 – making measuring faster and easier than ever before. Now in its current contemporary format, the STANLEY® Micro PowerLock® 3M/10' (19mm wide) Tape Measure features a strong, bright yellow 19mm blade with clear and legible markings and Class II accuracy providing a reassuring +/-0.5mm error tolerance at 1m, making it suitable for a multitude of professional applications. Compact and lightweight, this versatile tape has been specifically designed to fit perfectly in a pocket. Engineered to last, the STANLEY® PowerLock® Tape Measure has been treated with a polyester film-coated blade coating that delivers up to 10x more resistance to abrasion than a standard lacquered blade. The TRU-ZERO™ hook ensures precise inner and outer measurements, moving back and forth along the securing rivets to account for the hook thickness.
