Add this ring-holding fixture to your GRS Benchmate Encore QC or QCX, and you'll have access to the entire outside surface of any ring for engraving and stone setting work. Simply slide your ring onto one of the 10 expanding mandrels (13.5 to 22.5 mm diameters) and tighten the drawbar with the included hex wrench until the ring is secure. The tension can be adjusted so that the ring can be rotated on the mandrel or held stationary. Made in USA.

Not compatible with the Original GRS Benchmate.
