Helix 300mm Metric Triangular Scale Ruler, Red

Ruler works well for drawing scaled diagrams as part of a college course. Clwar and easy to use. Good value.

Does everything expected. Markings are clear and easy to read and the colour coding is helpful.

Functional scale ruler, useful for reading plans especially if parts are at different scales. The range of scales covered on the ruler is very good, and the different colours on each side of the ruler help when switching between scales.It is a bit plastic and feels quite delicate, i don’t know how long it would last in regular use. Perfectly usable for occasional and beginner use, but store carefully and don’t drop as the pointed corners are delicate, and If they get damaged it’s not a lot of use. Worth noting no storage case provided. Good value for the price.Helix make an aluminium version also available from amazon of this but it’s nearly twice the price, but worth considering if you need a more durable option.

I studied architecture at undergrad and it is very useful for this, it has most of the scales we used bar maybe one which was easy enough to work out using the other scales. As a student i travelled a lot and as a clumsy person I dropped it a lot so I can say that for a plastic ruler it is very durable until if course you try using a scalpel with it... that did not end well for my 1:100 scale but it still worked for measuring, just not for drawing straight lines. I had a metal version which was better for cutting but not so great for everything else. This product is very light compared to it's metal opposition, even the aluminium sort. It also doesn't make a horrible clatter and clang when you drop it in the middle of a silent studio. So yeah, great buy, great price, I would 10/10 recommend.

Just another tool in my technical drawing equipment. very helpful when working to scale.

Well built and easy to read.

Use to use one of these at college 30+ years ago and needed one suddenly to do some work, never forgot how to use it. Excellent piece of kit to have handy.

Nothing to say apart from good value and happy with purchase.
