Helix 45cm Tri-Scale Triangular Ruler

This is a great purchase, I bought it for the builders working on my extension so they can easily read off actual measurements. Works very well and would reccommend.

If you work in construction/architecture these are all the scales you will need. This ruler is easy to read and well made and will last you years.

Especially for model making, this is a wonderful ruler to have, and significantly better than the plastic versions that exist. The printing doesn't wear off, as it does on plastic ones, and the aluminium holds up well when used to cut with a scalpel - to scale!

Well made, easy to read, good value for money. Scales are painted on so could rub off hence 4 stars, but have had no issues so far. Couldn't find an engraved version for a sensible price.

Decent price. I wanted this to check a 'scaled' drawing, and then to draw my own. May come in handy again, if only as a general ruler. Until then it will hang up in the garage with the other tools.

Fantastic. Scale Ruler that takes out the guess work and maths when looking at plans. Study aluminium and clear markings.

I wanted to use this in combination with my cutting mat and knife. I probably should have remembered this detail from my school days but aluminium appears to be a soft metal therefore it is not ideal for using with a cutting knife as the ruler also cuts. I chose this because of the shape and I thought that it would keep my fingers safe if I slipped with the knife. It does the job perfectly for that purpose but perhaps a steel ruler would be better. It is not advertised to be used in the way that I have used it so bear that in mind when reading the review on this product. It is however a good quality item that looks to be well made. Use it for measuring and it is spot on!

Still using this bad boy now. Straight as ever while being nice and light. Have brought one from a local store which bent quickly and markings rubbed off. Not getting any issues with this one after this much time when it was less then half the price !

very good tool

E di aluminio molto utile per leggere piani

Der Artikel kam wie immer schnell und gut verpackt sowie unbeschädigt an. Alles genau wie beschrieben. Ich würde den 45 cm Dreikant jederzeit wieder kaufen. Benutze ihn, um mit einem Cuttermesser Papier / Ausdrucke zuzuschneiden. Dafür ist er perfekt geeignet. Was soll man mehr zu einem Alu-"Lineal" sagen? Viele Grüße NAM

Item arrives in good condition. I thought is was a plastic product but it has metal coating outside the plastic, which mades it even more rigid and durable. It was a good product.

Ha le scale architettoniche più usate comunemente, inoltre le dimensioni sono giuste, comodo da portare in giro! Davvero un bel scalimetro!
