12" Architectural Scale Ruler Aluminum Architect Scale Triangular Scale Ruler for Architects, Draftsman, Students and Engineers, Color-Coded (1 Pack)

I relied on my plastic architectural scale for three years in high school, and it served its purpose. Toward the end, however, the dents, dings, and scratches made it a less than precise tool. This time around, I wanted a scale that could survive drops off my workbench, but more importantly, give me easier to read markings that won't wear off. This aluminum rule fits the bill. It is heavy enough to stay put on your drawing board, and the edges are crisp enough to make accurate measurements without being dangerously sharp. I compared the graduations to a known precise rule, and they were dead on accurate. I believe this scale will last many years.

I always prefer metal rollers and scales because they tend to be more durable than plastic. This scale is no different. Very sturdy, and incredibly straight, with well-defined markings.I got the natural aluminum colored scale, and the finish is excellent. I used a .01mm precision calipers and I found no obvious errors.Watch the sharp corners, they can scratch or cut you if you are careless. As I don’t need the corners to be precise since the markings are inset a few mm, I knocked them down with a metal file.Great value for the material and accuracy.

Excellent quality

Very well made with clear markings. The color markings show you which side to use which is nice.

Very nice and durable.

This is the nicest architectural ruler I've ever owned. I've owned many over the years starting in the 70's when I was a Construction Management student. All of the others have been plastic. This Aluminum ruler is well marked, light weight, accurate and easy to read. I love the color coding for quickly returning to the scale I've been using.

Every thing you would expect. Every thing highly visible/easy to read. Accuracy seems fine, especially for my needs.

Solid and smooth with nice heft. Feels good in the hand and works great.
