Fantastic
Woody66ff•August 22, 2018

Very good quality
rudy moritz•June 17, 2018
At first I was skeptical of the heavier weight of the aluminum vs. the old one I had in plastic, but it turns out to be much better and more stable.
Nice and solid
VINCENT M.•June 16, 2018
Nice and solid. Only one thing, it's not absolutely flat. When placed on a piece of paper and pressed on, the paper can still move. You should only have to press on the ruler but in this case, you'll have to hold the ruler AND the paper: not very convenient.
Metal is formed nice, Markings are very close, but not 100% accurate
Keith Robicheux•June 11, 2018
This ruler is well formed, with smooth, flat edges, and a good surface finish. As far as the graduated marking go: they have a slight variance in several of the scales. The inconsistency in the markings is inconsistent, meaning that some of the markings are spot on, and others are slightly off. for example, on the 1/2 scale, the tiny one foot scale broken into inches is about a 1/32 or 1/64 shorter than a 1/2 inch, but the rest of the 1/2 scale markings equal exactly 1/2 inch. I didn't notice right away, but after using the ruler for a while using measurement that were too short, the discrepancies built up, and I was about an 1/8 inch off on a 26 foot wall in a scale drawing. So you wouldn't be able to do super accurate scale drawing with this ruler, but you can get close. I'm not a pro, so this works for my purposes. If you need more accuracy, you'll probably need a laser engraved ruler, or at least one with a guarantee for more precise markings.

Love this solid Architectural scale. Solid aluminum. Hefty weight, and looks professional!
