This complete ring sizing system pairs lightweight front-of-house mandrels with a heavier workshop mandrel and matching ring gauges, so every size from 1–16 reads the same at the counter and at the bench. The mandrels feel solid and precise in the hand, with crisp engraved markings that are easy to read under normal shop lighting.
Features
- Integrated ring sizing system designed to keep showroom and workshop sizing perfectly aligned from size 1 through 16.
- Lightweight aluminum marked ring mandrel (approx. 0.88 lb / 0.4 kg) optimized for secure handling in busy showrooms.
- Matching hardened steel marked ring mandrel (approx. 2.2 lb / 1 kg) ideal for bench use and ring work at the anvil.
- PrecisionFit 31-ring gauge set provides a full run of USA sizes 1–16 that matches the markings on both mandrels.
- All sizing components are manufactured to International Standard ISO 8653 for consistent, interchangeable sizing.
- Mandrels are machined, hardened, ground, and engraved for a clean finish and reliable, repeatable readings.
- Ergonomically designed handles give a firm, comfortable grip during frequent sizing checks.
- Each piece passes through a dedicated PrecisionFit quality control process to confirm accurate 1–16 sizing.

Notes
The PrecisionFit system is designed to eliminate the need for cross-referencing between mismatched ring sizers and mandrels. Use the aluminum mandrel and 31-ring set at the counter, and the steel mandrel at the bench, knowing all three components are calibrated to the same ISO 8653 standard.
