Helix 300mm Metric Triangular Scale Ruler

great product with a favorable price

I work as an electrician carrying out work on high end residential & commercial properties.I’m forever working with detailed drawings & plans. This scale ruler is invaluable & enables me to carry out work to precise measurements

Fairly inexpensive, there are, nevertheless, a good range of scales from 1:2 to 1:2500, set in pairs along 6 edges. The feel is a bit plasticky, but that is what it is and there is a bit of flex in it, but not much. All-in-all, this represents good value for money without being of the highest quality, although there is no reason why it shouldn't last out a career despite being student quality. I have bought several scale rules over the years, in both plastic and aluminium and can honestly say that this does the job although it is less weighty and has less of a quality feel about it than much more expensive scales. Over time the scales and markings might wear since it does not come with a case, but a good scale rule to start off with.

Does the job, it measures perfectly and is straight.
