Bump Rolling
Get an accurate measurement of the radius without the hassle of making metal or cardboard arcs, then adjust the arc accordingly.
Introducing the ARC MASTER Universal Radius Gauges with Variable Arc
TAKE THE MYSTERY OUT OF WORKING WITH ARCS
It is now possible to measure the curvature of an arc quickly, easily, accurately and inexpensively.
Instantly measure anything from hand-railing, to front-end loader buckets to door-way arches.
Model IRG 3600
Inside Radius Measurements
Measures radii ranging from 6"(150mm) to 144"(3600mm) in Metric and Imperial, from the Inside. Ideal for construction workers, welder-fabricators, hobbyists etc. to take a quick and easy measurement in the field to help describe an arc and putting it down on paper. Taking a radius measurement and then measuring the arc-length would be all the information required to take back to the shop.

Arc Master Accessory
The VARIABLE ARC is a unique tool that, when mounted onto the RG 3600 radius gauges, will actually form the arc the radius gauge is set to.
The Variable Arc is perfect for measuring arcs drawn on paper as is so often the case in metal or wood shops. Also, because of the measuring capability of the Arc Master Radius Gauge, the Variable Arc is readily scaleable, ideal for use in drafting arcs.
