Precision Fit Adapter for Sub-1oz Gold Assay Cards – Add-on for 1oz Universal Assay Card Box

Convert Your 1oz Box for Sub-1oz Cards

These precision-engineered adapters transform your Universal Assay Card Box into a versatile storage solution for smaller gold cards. No more rattling or loose fits—these adapters slide directly into existing slots to securely hold your fractional gold assay cards alongside your 1oz collection.

Key Features:

• Custom-Engineered Fit: Designed specifically to friction-fit into our existing Universal Assay Box architecture—no tools or glue required.
• Eliminates Rattling: Keeps smaller cards upright and perfectly centered, preventing them from sliding side-to-side in the slots.
• Universal Compatibility: Fits most sub-1oz assay cards (Valcambi, PAMP, Royal Canadian Mint, IGR, etc.) that are narrower than 50.5mm wide.
• Seamless Integration: Simply slide the adapter in to instantly upgrade your existing storage system.
• Mixed Storage Capability: Organize your entire stack by mixing 1oz cards and fractional cards in the same storage box.
• Supports Multiple Sizes: Perfect for 1g, 5g, 10g, 20g, and narrow 1oz cards like IGR that don't fit standard slots.
