Graduated Metal Beam Compass Set

Draw large, accurate circles and arcs with the Pacific Arc Professional Graduated Beam Compass. Made in Germany, this precision instrument includes two 13-inch beam bars that can be joined with the included coupling to draw circles up to 48 inches in diameter.

The bars feature inch and metric graduations for easier setup and measurement. Sliding leg assemblies lock securely in position, while interchangeable drawing components allow the compass to be used with a lead holder, ruling pen, or divider point.

Ideal for professional drafting, architecture, engineering, geometry, woodworking, construction layouts, and other projects requiring circles larger than a standard compass can produce.
