Coopay Large Triangle Ruler Set Square, 30/60 and 45/90 Degrees, Triangle Hollow

I usually preferred Alvin or Westcott for my drafting rulers and templates. This set of triangles caught my eye for some different reason. I guess it is the overall size of them for a decent price. the triangles are crystal clear. They ARE NOT cheaply made by no means. The scaling is emboss on the backside of the triangle. Even has a clear vinyl case for them. The only complaint: Supposedly, it was in stock, but took nearly 2 weeks to get it in my hands

I needed this to speed up closet lining in my new place.

As an engineer, I was required to learn fundamentals of drafting long ago in both high school and college. As a retiree, now with computer-based drafting programs, the skill I use most is coordinating triangles to sketch parallel and perpendicular lines, mostly when sketching preliminary ideas for something I'm want to build in my shop. My other use is setting miter gauges accurately on one of my saws. These triangles are great for both of these applications, without breaking the bank. As closely as I can measure, the 30-60-90 and 45-90 angles are spot on, and the triangles are sturdy and a nice size. Perfect!

None,

I was surprised how good they were.

Did the job.

Why did you pick this product vs others?: Perfect for the office and my woodshop.

These triangles are the perfect size to carry on my backpack for some of my architecture classes. Very sturdy glide well

Bonjour, je suis content de les avoir ,mes une seule chose m'inquiète le plastique est régide et j'espère quelle ne craquerons pas quand, je vais les échappées mes j'apprécie les règles un côté impériale et l'autre est métrique donc sa ses pratiques merci.

I like the size and they are good quality

Good quality! Right size for me!

I like the feel of these - they are nice and thick, and accurate. My set square is a bit warped and curls upward, making for some challenges during drafting, but they do the trick. I paid extra hoping they would be better quality, but I personally think they’re overpriced.
