Gold & Platinum Finger Fit Expandable Ring Shank 3x3mm

The Finger Fit is an expandable, hinged ring shank designed to solve one of the most common fitting challenges in jewelry: rings that fit over the knuckle but are too loose on the finger. The shank opens, allows the ring to pass over the knuckle, then closes and locks for a comfortable, secure fit — no resizing required.

These Finger Fit shanks measure 3mm x 3mm in shank diameter and are available in 14K Yellow Gold, 14K White Gold, 18K Yellow Gold, and Platinum. Two size ranges are offered to cover most finger sizes from 2 through 9.

Features

• Easy installation: Finger Fit shanks attach to an existing ring without redesigning or creating a new setting — making the upgrade simple for any jeweler or trade shop.
• Die-struck and CNC machined: Precision manufacturing produces a shank that is stronger and more durable than a cast equivalent. It can be heated and soldered without damaging any components.
• No key or pin required: The shank opens and closes without any external tool. A cover catch provides a guaranteed close with no tension mechanisms to loosen over time.
• Guide wire security: A built-in guide wire bridges the gap when the shank is open, preventing the ring from falling off or flying open. Guaranteed to open 3 full sizes.
• Individually replaceable components: Every part of the shank can be replaced independently, extending the working life of the ring without requiring a full shank replacement.
• Trade-proven: Tested and trusted by over 5,000 retail jewelers and trade shops.
