  • Clearly one of the best small squares out there
Size: No Size Style: 1904-0450
Super handy size of this square makes it a must have around the wood shop. Love the white on black easy-read markings. The price is right and it seems to be a quality tool. Was going to pay the price for one of those fancy smaller squares, but glad I didn't. For what I would have paid, I could have three of these. Will definitely get another one to have as a spare. ... show more

  • Pay attention to the size 4.5"
Size: No Size Style: 1904-0450
This is perfect for a 2x4, but I did not note the size (despite being in the description), I went by the picture, as it came up with all the other framing squares. I was expecting the larger square. But nonetheless, it works great for 4" lumber.

  • Easy to read and just the right size for up to x 4 wood
Size: No Size Style: 1904-0450
Scale is easy to read and just the right size for small jobs or 1 x 4 and 2 x 4 wood.

  • So far so good !
Size: No Size Style: 1904-0450
Sticker came right off cleanly, maybe they fixed the problem .. the square itself is really lightweight, hoping it doesn’t dent up easily ..

  • Nice little compact square
Size: No Size Style: 1904-0450
The negative reviews about the sticker proved to be quite useful as it gave me the heads up to use a heat gun and the sticker came off rather cleanly. Other than that, good solid little square.
