- Descripción
The roller ruler allows the creation of hachures with exactly parallel lines with even spacing without using a T-square. A roller is integrated into the ruler which makes it possible to slide the tool in a parallel manner without slipping or shifting. The roller is in turn outfitted with a graduated scale which displays to the millimetre how much distance has been covered. The holes every 10 mm near the ruler’s edge allow parallel vertical lines to be made as well: you put the pen in a hole and push the whole unit up and down and repeat as necessary.
Regla rodillo M+R l = 300 mm, No. 8400
