UltraTech 9659 Extender Kit for Hard Top Plus, Adds containment for 4 additional drums. With Drain.

The UltraTech 9659 is a 4-drum extender kit designed to expand existing Ultra-Hard Top Plus spill containment systems beyond their standard drum capacity. The kit includes a middle wall that installs between the existing Hard Top unit and the new 4-drum section, allowing facilities to scale their outdoor drum storage incrementally without replacing the base unit. Multiple extender kits can be chained together to accommodate operations that grow beyond 20 drums, making this the preferred solution for facilities that require large-scale, lockable outdoor drum storage with secondary containment. The drain version allows controlled sump drainage from each compartment independently.

• 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 systems beyond 20 drums with no practical upper limit on configuration size
• Includes Middle Wall for Integration – Kit ships with a middle wall that connects the new 4-drum section to the existing Hard Top unit, maintaining the structural integrity and weatherproof enclosure of the complete system
• 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 Sump per Compartment – Each 4-drum compartment maintains its own 75-gallon containment sump with internal walls, allowing incompatible materials to be segregated within adjacent compartments across the extended system
• Drain Included – Integrated drain per compartment enables controlled sump drainage; all-polyethylene construction resists rust, corrosion, and a broad range of chemicals for long-term outdoor service
