Squares & Protractors

In stock

Measuring squares consist of two straight edges set at a 90-degree angle to each other. The primary purpose of these measuring tools is to check the accuracy of right angles to ensure that components remain perpendicular. Similarly, protractors are a measurement device used to measure angles.
