Barrel Racking vs Drum Racking

[Broken Anvil Distilleries]

We are in an industrial town and we have many suppliers of racks for 50 gallon barrel drums. Local suppliers arent certain if they differ in sizing to wine / whisky barrel racks . By photo they look the same but was wonderkng if anyone out there could clarify this for us. We can order in wine barrel racks and pay shipping if needed, but are trying to source local for anything possible. Are drum barrel racks good to use? (or identical?). We are looking at the standard 2 barrel forkliftable racking most distilleries seem to use.

Thanks in advance.
