Triangular scale
Well the one that is pictured is not the one that was sent .we ordered 4 all together and they all were the wrong one. So we kept them hoping that they can be put to use somehow.

Same scale our architect uses
Needed the scale to review the drawings from our architect. AFAIK this brand is the standard of the industry. Color coded to make it easy to locate the scale you want - a big help with 10 scales plus a 12 inch ruler.

Classic drafting tool
Gets the job done. I was happy to be able to walk into the store and purchase immediately from a well-stocked shelf as the item was needed immediately.

It's a scale for drafting
It's made of plastic so may not work well as a cutting guide. Works fine at defining dimensions on drawings and sketches

Architecture Ruler
I was disappointed in the ruler that I just purchased. I have had that same ruler manufactured by that same company for the past 30 years and this new one is not as strong as the last one.
