IRG-3600 Radius Gauge measures the inside radius and diameter of cylindrical objects. The diameter measurement is calculated by doubling the radius measurements. This is an essential tool for acquiring quick measurements for large pipes, metal rolling, or fabrication and measuring large tanks.
Items comes with a Variable Arc, a durable device that when mounted on the IRG-3600 can form the arc of the radius you have set on the gauge. Perfect for creating scaled models, drafting buildings, arch way construction, millwork, and more.
