Closeout Jura by GRS 502-015 Brass Shellac Cylinder

The Jura by GRS 502-015 Brass Knurled Shellac Cylinder is designed for securing delicate rings using shellac on the Jura by GRS Quick Change Ring Holder. When tension from collets must be avoided, this brass cylinder provides a gentle, reliable alternative for holding fine rings during engraving or stone setting work.

The cylinder features fine horizontal knurling along its surface. These lines serve a dual purpose: they help shellac adhere firmly to the cylinder during use, and they assist with clean removal when the work is complete. This thoughtful detail makes the cylinder especially well suited for very delicate rings that require extra care in fixturing.

This accessory is intended for use with the Jura by GRS Quick Change Ring Holder, which is a core component of any Jura by GRS QC System Kit or Jura QC Kit.

• Brass construction for gentle, non-damaging ring support
