The Moore & Wright Traditional Inside Spring Joint Calipers are precision measuring and comparison instruments designed for checking and transferring internal dimensions in engineering, machining and workshop applications. Manufactured from polished tool steel, these traditional inside calipers provide a practical solution for comparing internal diameters, openings and other internal features where direct measurement may be difficult.
Featuring a bow spring mechanism, the Moore & Wright Inside Spring Joint Calipers maintain uniform tension throughout their working range, allowing controlled adjustment of the measuring legs. A centrally mounted adjustment screw provides finer setting than traditional firm joint calipers, helping users establish and maintain the required opening when comparing or transferring internal measurements.
Available in six sizes ranging from 75mm (3 inches) to 300mm (12 inches), the Moore & Wright Traditional Inside Spring Joint Calipers offer a choice of instrument sizes to suit different measuring requirements. Their polished tool steel construction and fine adjustment mechanism make them suitable for toolmaking, component inspection, precision engineering and general workshop measurement.
