Customer Reviews

Combination Square is rated 4.6 out of 5 by 9.
Rated 5 out of 5 by from really cool combo square The combo square was just what I needed although it was a bit loose but precise enough for the task at hand. Sometimes I just sit and look at it and am encouraged to do another task!

Rated 2 out of 5 by from Cheap Alternative but not Reliable The combo square worked out for some quick simple jobs in a pinch but it was not even 75% accurate. The level was not reliable and the square has play. If you are looking for professional grade, spend the extra $ and get a good combo square.

Rated 5 out of 5 by from Combination Square Bought it to put down laminate flooring. Could not do job without it. Using ofr end cuts and cuts around obstacles. Makes the job much easier than it would be without it. Would not reccommend doing a flooring job without one.
