Werka Digital Protractor Squares

Squares check squareness and angle. The DIN875 grade (00, 0, 1, 2) is the square's accuracy: 00 and 0 for inspection, 1 and 2 for the workshop and marking out. A square with a base sits on its own stock; a knife-edge square reads by the light gap. Protractors and protractor squares measure angles other than 90°. This family comes in 3 options: 120x150mm, 150x200mm, 200x300mm. The order code of each is in the specification table; quote the code when you ask for a price.
