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

Great quality

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.

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.

Nice in all aspects except one. This is a solid block of aluminum and is a little heavy in moving around drawings, desktops, etc. The corners are also a little sharp!I replaced a lost plastic....plastic is lighter and easier to move. Aluminum is solid and will last forever.

Great quality for a fair price.

Nice ruler with multiple measure units.

This purchase was to replace the one I’d had since college, which despite being a name brand was plastic and finally cracked after nearly 40 years of use… I don’t foresee ever having to replace this one.
