This multi-functional square lays out squares and right angles while also measuring angles with ease. Featuring a built-in easy angle readout, it allows you to mark 30-degree and 45-degree angles accurately.

Constructed with a sturdy yet lightweight aluminum body, it includes inside and outside scales for measuring and marking workpieces. Two quick angle finders help with 30 and 45 degree angles, and elongated marking notches ensure accurate line scribing. The removable anodized aluminum fence can be used for laying out circles or working on flat surfaces, sliding along the edge of your workpiece to keep scales ly perpendicular.
