Most hanging file cabinets have adjustable hanging rods or bars and list compatibility with standard sizes such as Letter, Legal, A4 and F4.
Many models include keyed locks or a central locking system that secures all drawers. Some designs add drawer-interlock mechanisms that limit how many drawers can open at once to help prevent tipping.
Mobile cabinets typically ride on swivel casters. Common setups are four 360° casters (two lockable) or five universal casters with two brakes—allowing easy relocation and the ability to lock the cabinet in place.
Common materials include metal/steel frames and engineered wood panels such as particleboard and MDF, with some cabinets using wood-framed construction.
Capacities vary by model. Typical listings show file-drawer ratings from about 22 lb up to 55 lb per drawer (some note 55 lb per drawer / 110 lb total), a small-drawer rating around 11 lb in one listing, tabletops/countertops listed roughly 100–155 lb, and one wood cabinet listing overall support up to about 220 lb.
Common stability features include drawer-interlock systems, anti-tip/anti-topple kits or devices, adjustable or replaceable feet, and lockable casters on mobile units.
Many cabinets use full-extension drawers with quiet ball-bearing or steel slide rails, allowing smooth operation and full access to hanging files.
