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

Model IRG 3600<br />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.

Model ORG 3600
Outside Radius Measurements

Model ORG 3600<br />Outside Radius Measurements

Used where straight lines are few and far between, the ARC MASTER Radius Gauge weighing in at only 12 oz., will be an indispensable addition to anyone's tool kit. A sensible low-tech solution to a high-tech problem. Measures radii ranging from 6"(150mm) to 144"(3600mm) in Metric and Imperial, from the Outside.

The Variable Arc
Arc Master Accessory

The Variable Arc<br />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.
