5" Incra Square

There is more to like about this square than just its guaranteed accuracy! This is perhaps the most intelligently designed square I have ever used. First, the anodized one piece alloy blade is incredibly thick at 1/4" so it can withstand the occasional trip to the floor and still maintain its accuracy. Next, the interior corner is relieved, so that you can mark right to the edge of a board. Finally, side bolsters are flush to the bottom edge for stability, but set back from the interior edge by 3/16 inch, providing an easy to use support lip for marking and layout. Now about Incra’s guarantee: the squares will maintain an angular deviation of less than 0.001" from the nominal at any point along the full length of the blade! Note, actual blade length of 7" squares measure 7-5/16". Made in USA.
