525442-7 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 both go (green) and no-go (red) measurement slots for wire size verification, with labeling that displays the wire size in AWG and corresponding measurements. This gauge is calibrated and certified, making it suitable for quality control, wire assembly verification, and field inspection applications where accurate wire gauge confirmation is essential.
