The 275 and 330 gallon CageBuster totes share the 48 x 40 in pallet footprint; the extra 55 gallons comes from height (52 in vs 58.75 in). Check door, rack and trailer clearance before switching sizes.
Caged totes cost less up front. An all-plastic tote has no cage to bend, repair or replace, so it fits closed-loop programs where the same tote makes many trips. Bonar's CageBuster is UN 31H2 certified for packing group II and III hazardous materials.
Composite IBC means a plastic bottle inside a steel cage. If you already run caged totes, Bonar states the CageBuster valve and lid threads fit many caged IBC components, and a 2 in replaceable bung port is optional, so most of your fittings and pumps carry over.
Smaller fills: the 500 L (135 gal) CageBuster suits lower-volume products and tight floor space.
For chemicals, see the chemical and ag-chem IBC range with 3-port and 4-port containers.
