portable filing cabinets

Most units accept standard hanging files — typically Letter and A4 — and several models explicitly state they also accommodate Legal-size files.

Many models include casters or wheels for easy repositioning. Common features are locking casters or brakes for stability and multi-wheel setups (four- or five-wheel) that improve balance and maneuverability.

Common materials include medium-density fiberboard (MDF), wood, and steel.
