locking file

Most locking file cabinets include adjustable hanging rails that accept common sizes such as Letter, Legal, and A4. A few product descriptions also list support for F4 files. Check the cabinet’s hanging-rail specification to confirm compatibility before purchase.

Options range from lockable rolling casters (which can be engaged or removed for stationary use) to multi-wheel mobile designs with front-brake casters. Some mobile units include an anti-tilt center caster for added stability. Under-desk cabinets may arrive fully assembled with only the casters left to attach.

Many metal cabinets use an anti-tilt interlocking mechanism that restricts opening to one drawer at a time to prevent tipping. Mobile under-desk models may also include an anti-tilt center caster to improve stability when drawers are extended.

Manufacturers often omit numeric per-drawer capacities and instead use terms like “heavy-load” or “heavy-duty.” One listing specifies 55 lbs per drawer, but that is not universal. Always check the product specification or load rating for the specific cabinet you’re considering.
