The Finger Fit is an expandable, hinged ring shank designed to solve one of jewelry's most common fit challenges. The shank opens to allow the ring to pass over the knuckle, then closes and locks securely for a comfortable, snug fit. Available in 14K Yellow, 14K White, 18K Yellow, and Platinum, these shanks measure 2mm x 2mm in diameter and are offered in two closed-size ranges to accommodate a wide range of customers.

Features

  • Simple installation: Finger Fit shanks attach to an existing ring without requiring a full redesign or new fabrication.
  • Die-struck and CNC machined for precision and durability—stronger than a cast ring shank.
  • Heat and solder compatible: Finger Fit shanks can be heated and soldered without damaging any components.
  • No key or pin required to open; cover catches provide a guaranteed close with no mechanisms that loosen tension 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.
  • Opens 3 sizes to provide sufficient clearance for larger knuckles.
  • Individually replaceable components extend the life of the shank—worn sections can be repaired without purchasing an entirely new shank.
  • Tested and proven by over 5,000 retail jewelers and trade shops.
