End-Tab Folders vs. Expanding File Wallets
Comparing 2 standards across 12 specifications. 12 key differences identified.
End-Tab Shelf Filing Folders (designed for open-shelf modular lateral file systems) feature an extended full-cut vertical tab along the right-hand vertical edge rather than the top. Standard in hospital medical record rooms, dental clinics, and insurance claims departments, they utilize color-coded numeric and alphabetic Mylar labels.
Expanding File Wallets (accordion expanding jackets made of heavy red rope paperboard or Tyvek) feature multi-fold expandable side gussets ranging from 1.75 inches (400 sheets) up to 5.25 inches (1200 sheets). Equipped with protective top flap closures and elastic cord ties, they are standard for real estate closing packages and tax audit portfolios.
