The UltraTech 9658 is a 4-drum extender kit designed to expand existing Ultra-Hard Top Plus spill containment systems beyond their standard drum capacity without an integrated drain. The kit includes a middle wall that installs between the existing Hard Top unit and the new 4-drum section, allowing facilities to incrementally scale their outdoor drum storage in a closed-containment configuration. Each compartment maintains its own separate 75-gallon sump with no bulkhead fittings connecting adjacent sumps, allowing incompatible materials to be segregated across compartments. Multiple extender kits can be chained to build systems beyond 20 drums with no practical upper limit.
- Scalable Drum Storage Expansion – Adds one fully enclosed 4-drum compartment to an existing Ultra-Hard Top Plus system; multiple extender kits can be added in sequence to build outdoor drum storage systems well beyond 20 drums
- Includes Middle Wall for Integration – Kit ships with a middle wall, two sets of roll-top doors, and two sets of swing-out doors that connect the new 4-drum section to the existing Hard Top unit while maintaining a continuous weatherproof enclosure
- 9,000 lb. Load Capacity per Compartment – Uniformly distributed load rating per compartment accommodates fully loaded 55-gallon drums and IBC tanks stored within the extended system
- Separate 75-Gallon Sump per Compartment – Each compartment maintains its own independent containment sump with no bulkhead fittings between sumps, allowing incompatible materials to be safely segregated in adjacent compartments
- No Drain Configuration – Suited for facilities where closed containment is preferred or required; sump contents managed through periodic pump-out; ships partially unassembled for freight savings
