Modular / Expandable
Modular / Expandable indicates whether a rack can accept additional compatible shelves or modules.
An expandable design can allow the arrangement to change as equipment is added or replaced. Expansion may involve stacking modules, fitting longer supports or adding separate sections. The feature does not specify which parts are included or how far the system can be extended.

Check the permitted combinations, maximum height and load limits for the completed arrangement. Adding a shelf does not automatically increase the total weight the rack can support. Extra modules may also alter clearances, stability and any requirements for securing the rack.
Confirm compatibility with the exact rack version before buying expansion parts; similar-looking components may use different fittings or dimensions. Plan ventilation space and access for cables after the change. Modularity describes a supported way to reconfigure the structure, not permission to improvise extensions or combine unrelated furniture parts. Follow the assembly sequence and unload equipment before structural changes.
