Orientation Gauge

The Otto Frei Jewelers Orientation Gauge was developed with goldsmith Doug Zaruba to make layout and symmetry checks fast and repeatable at the bench. Use it to find centers, set precise angles, and verify straightness like a machinist’s square. Clear acrylic with an etched 2.5 mm grid lets you see the work while you align. Small rubber feet grip smooth surfaces for stable scribing and measuring. Made in the USA.
