Review: Okay, a triangle rule, such as this can be a real help when drawing out architectural plans (I'm no pro, but have done many times, for our needs, over the years) and, this one doesn't disappoint. I read most/all reviews before purchasing and am not unhappy, in any way, with it. Accurate, clear, large-enough markings to use well -- no "oops" in the making of this product, where one might feel like it's an inferior product. ## Features - Perfect ruler for architects. - Three sides with six different scales. - Open divided: 3/32, 1/8, 3/16, 1/4, 3/8, 1/2, 3/4, 1, 1 1/2, 3" = 1 foot. - Full divided: inches to 16ths. - White plastic. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001E67XZ4 | | Brand | STAEDTLER | | Colour | Blue | | Customer Reviews | 4.5 4.5 out of 5 stars (401) | | Global Trade Identification Number | 00031901901462, 00031901907105 | | Graduation Range | 12 Inches | | Item Dimensions L x W | 39.4L x 5.1W centimetres | | Item Weight | 0.11 Pounds | | Manufacturer | Staedtler | | Manufacturer Part Number | 987 18-31BK | | Material | Plastic | | Model Number | STD9871831BK | | Style Name | Triangular | | UPC | 031901901462 785525489959 031901907105 638458808062 799916110117 799198363058 635665122233 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** STAEDTLER - **Colour:** Blue - **Graduation range:** 12 Inches - **Material:** Plastic - **Style:** Triangular ## Images ![Staedtler 12-Inches Architect Triangular Scale (98718-31BK) - Image 1](https://m.media-amazon.com/images/I/614R24CsB7L.jpg) ![Staedtler 12-Inches Architect Triangular Scale (98718-31BK) - Image 2](https://m.media-amazon.com/images/I/51hfObGbzAL.jpg) ![Staedtler 12-Inches Architect Triangular Scale (98718-31BK) - Image 3](https://m.media-amazon.com/images/I/51UUuFwgEAL.jpg) ![Staedtler 12-Inches Architect Triangular Scale (98718-31BK) - Image 4](https://m.media-amazon.com/images/I/61oW9BK9o0L.jpg) ## Available Options This product comes in different **Item Package Quantity, Style** options. ## Questions & Answers **Q: Where is it made?** A: I suspect Amazon has linked this review to multiple similar items as it has on others because I do not doubt the others who say their rulers were made in Germany. But, as the previous commentator replied, the description says this one is made in Japan. Another possibility, the seller has switched items but not updated the ad? **Q: Does it have architect and engineering scale ?** A: It only has the architect scales. **Q: Does it read 1/8? I need a Architect scale 1/8 for class, was just making sure this was the correct size scale.** A: Yes it has 1/8, 3/16, 1/4, 1/2, 3/4 , 1" and 1 1/2". Happy New Year **Q: What's the difference between a student and a professional architectural scale? The professional obviously costs more.** A: I believe the difference in cost is due to the professional scale having the markings etched into the scale. A student model simply has the measurement markings painted on to the scale. If you don't subject the scale to constant use buy a student model, it's accurate enough for DIYers. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***A on 9 June 2020* Ligero de buena calidad. ### ⭐⭐⭐⭐⭐ Review *by G***E on 9 June 2014* Okay, a triangle rule, such as this can be a real help when drawing out architectural plans (I'm no pro, but have done many times, for our needs, over the years) and, this one doesn't disappoint.
