BenchMate ring holder

The GRS ID ring holder redefines holding of rings. By tightening the clamping axle, the clamping sleeve is pressed into the clamping cones on both sides. This creates uniform pressure and spreads the clamping sleeve evenly. This holds the ring securely on the inside. When using the standard cone, the tension can be adjusted so that the ring can rotate easily during engraving. In contrast, the clamping cone locks the clamping sleeve so that the ring is held in a fixed position. This allows for secure stone setting. The ring holder is a good, affordable choice if you are looking for a simple, functional, and high-quality solution.
