Like all Incra Rules, this protractor is engraved in .010” thick stainless steel. All markings and through features are incredibly accurately placed to ensure exact markings on your work piece.

The 6” protractor covers all angles in ½ degree intervals as well as longer slots for the most common angles. You'll find this tool to be ideal for accurate placement of lines on any piece of wood.

The anodized aluminum handle is held in place by two thumb screws and also has a calibration lip to ensure precise re-assembly and alignment.

Works with any .5MM pencil lead (one included).
