0-180° Internal External Angle Finder

A versatile plastic angle gauge capable of measuring internal, external, and sloped angles with consistent reliability. Its four-segment hinged body uses a brass locking nut for precise, repeatable adjustments and secure angle holding. Built from robust ABS plastic, it delivers long-term resistance to impact, abrasion, and environmental stress in active workshop conditions. Dimensions when fully extended are approx. 15.5 x 9 cm (6.1 x 3.5 inches), balancing portability with functional scale. Used widely in cabinet installation, stair building, and custom furniture fabrication where angular fidelity directly affects fit and finish.
