Vertical Drum Storage Cabinets safely house one or two 30- to 55-gallon drums. All cabinets are supplied with a removable, adjustable half-depth shelf to store Class III materials or spare accessories such as drum funnels, vents and antistatic wires. Cabinets are also designed to accommodate a drum equipped with a pump or funnel so the cabinet may be used as a pumping station or for waste accumulation. Cabinets are offered with and without roller assemblies which facilitate the movement of heavy drums.
