Step Up!

The black lettering/numbers make this much easier to see. Square is solid! The added book and layout tool are huge bonus! Makes a great fence for my skillsaw as well. Highly recommend it, especially with this price point!

Good middle size

I have a traditional carpenter's square and a small plastic triangle, but this fills a size gap between the two. I've already used it for a lattice on a trellis I built and they are very square.
