Most black lateral file cabinets include keyed locks—either a single central lock or dual cam locks—with keys supplied. Many models also use drawer interlock systems that prevent multiple drawers from opening at once for added protection.
Drawers typically run on ball-bearing or steel ball-bearing full-extension slides, providing smooth, quiet operation and full access to the drawer interior. Several listings describe these slides as silent or ultra-quiet.
Most listings state that adult assembly is required. Some cabinets include the necessary tools or partial tool sets, while others do not—packaging typically notes whether tools are supplied. Many listings emphasize clear instructions or advertise easy assembly.
They commonly support hanging folders for Letter and Legal sizes and are often compatible with A4 folders; several listings also explicitly note compatibility with F4.
