About CMU Square

At CMU Square, our mission is to provide masons a NEW tool. As masons, we've been doing the same thing since prehistory and it works but there hasn't been a new tool in a millennia or so. We use what there is and make it work. So you see bricklayers using a carpenter's square without ever intending to hand-frame a hip roof or find the angle to cut facia. Throw that triangle at a carpenter and buy a tool for masonry. The CMU Square was invented by a mason, with every part of it designed for masonry. Not carpentry. It's a 3/8'' shim, a jointer and a tape measure made to mark cuts block and brick. Its the best thing to happen to making cuts since the saw.
