525441-3 is a wire/slip gauge handtool package designed for measuring and verifying wire sizes according to AWG (American Wire Gauge) standards. The gauge package includes a wire/slip gauge handtool, a storage box (part number 523225-3), and a gauge-specific certificate of calibration to ensure measurement accuracy. The tool features go and no-go size indicators marked in green and red respectively, with wire size measurements displayed in AWG format and corresponding decimal inch dimensions (such as 0.188 inches for reference). This gauge is calibrated and certified with a certificate number and manufacturing date (week/year) for traceability. The tool is commonly used in electrical assembly, quality control, and wire verification applications where precise AWG measurement and compliance verification are required.
