Customer Reviews

Carpenter Square is rated 2.0 out of 5 by 5.
Rated 1 out of 5 by from Beware this square can mess your project up The graduation on the long leg of the square are off by 1/16" and on the short leg there off by 1/32" and it's stamped MADE IN U.S.A., that nice. This is going back to the store and I will ask them to take it off the rack and get my money back. A kids toy scale is more accurate then this.

Rated 1 out of 5 by from Not Square, Inside and Outside Marks on Both Legs Are Incorrect Been using this square for a while and couldn't seem to get anything cut square. Finally decided to compare to my Lufkin machinist combo square and a number of other rulers and they all agree that this square is off. The picture I've attached isn't the best, but you can clearly see at the 2" mark on the long leg that the square in question (on the left) is off by at least 1/16. The inside is even worse, and the same with the short leg.

Rated 1 out of 5 by from Inaccurate..... useless and thus junk! What a shame that this tool hits the shelves at HD! It is not square (at least 0.5 degrees off) and the scale reading is off by at least 1/32". And for the patriotic ones, it's made in the USA.

Rated 2 out of 5 by from Rusted This tool surface rusted quite a bit, making it very difficult to read the measurements.
