The Faithfull Prestige Angle Gauge is manufactured from aluminium using computer numerical controlled (CNC) machines. The black anodised finish offers enhanced corrosion protection and the laser engraved scales give outstanding measurement accuracy. The protractor features laser etched graduations from 0-180°. It is used to determine existing angles, as well as creating new angles, setting bevels and transferring angles from one surface to another. A knurled thumb-nut allows the rule to be locked at a chosen angle.Additional Information:Gauge Type: Angle Gauge
