While they vary greatly in form, these tools are all dedicated to single function: marking and checking 90° angles. From squares small enough to slip into a pocket to a full-size carpenter’s square, we offer try squares, combination squares, rafter squares, double squares and more. Invaluable for layout, calibrating power tools, checking assemblies, and other tasks where accuracy is important, this line includes precision-made tools from Veritas, Starrett, Bridge City and other leading manufacturers.
