3-in-1 Adjustable Combination Ruler, Square & Protractor

3 Essential Measuring Tools in One Reliable Instrument

The 3-in-1 Multi Combination Adjustable Ruler combines a straight ruler, square angle finder, and protractor in a single, robust tool designed for accurate measuring and layout work. Manufactured from hardened, tempered stainless steel, the blade resists bending and wear, providing consistent performance over time. All components are securely joined with brass screws and scribes, ensuring smooth adjustment while keeping every part firmly attached.

This combination ruler features a 300 mm stainless steel blade with both metric and imperial graduations for versatile use in school, workshop, or office environments. The square and protractor heads are equipped with integrated spirit levels to assist with alignment and leveling tasks. The protractor head measures angles up to 180° and is reversible and clearly graduated, allowing for precise angle marking and checking on a wide range of projects.
