Made in England by Durston, with six splines on its polished steel mandrel, this high-quality ring stretcher ensures exceptionally accurate ring sizing. This sizer will size non-ferrous precious and non-precious metal rings and bands up to size 14 (U.S.). Its countersunk, polished steel, reducing plate will reduce bands up to 12mm wide.
The body is cast iron, powder-coated for long service life, and is drilled with four countersunk holes (7.5mm dia.) for mounting securely to your work surface (hardware is not included).
