Aristo Professional Scale Rule B Architect 30cm
The triangular ruler with the reduction scale 1: 100 / 1: 200 / 1: 250 / 1: 300 / 1: 400 / 1: 500 (B) is ideal for architects and architectural offices.
The triangular scale is primarily intended to remove dimensions in scale-printed plans and to be quickly converted accordingly.
Each side of the ruler has two scales. The three grooves are different in colour, so that the desired reduction can be found quickly.
The ruler is 30 cm long and made of white plastic.
