The Versa Ruler is a scalable system of rulers which allows for the fluid creation of unlimited, multi-sided shapes. Create joints by snapping rulers into the sliding protractor assemblies. Connect 2 or more rulers and create closed shapes that are both scalable and lockable. Rulers pivot and slide along their lengths-- and can also be connected end-to-end for extended lengths and proportions.
