Built with Durston’s award-winning design and engineering expertise, this ring sizer allows you to easily stretch and reduce rings and bands up to size 14 (U.S.). A specially designed gear reduction ensures effortless forming and also makes the stretcher great for bending and shaping rings using half-round, flat, oval ring stock up to 4mm (.157”) thick.

The ring sizer features six splines on the polished steel mandrel, ensuring exceptionally accurate ring sizing. Sixteen countersunk dies on the polished steel reducing plate reduce bands up to 12mm wide. Two ring bending dies for flat and domed material are included.

The body is cast iron, powder-coated for long service life, and the base is drilled with four 7.5mm dia. (.29”) countersunk holes for mounting securely to your work surface (hardware is not included).
