525446-4 is a wire/slip gauge package designed for hand tool wire size verification applications. The gauge package consists of a wire/slip gauge hand tool, a storage box (part number 523225-3), and a gauge-specific certificate of calibration. The gauge features wire go size (green) and wire no-go size (red) markings for quick pass/fail inspection. Each gauge is labeled with TE part number, revision, wire size (AWG), go/no-go dimensions, certificate number, and date of manufacture. This gauge package is commonly used in quality control and manufacturing environments to verify proper wire crimp dimensions and ensure consistent connector assembly.
