UltraTech 9658 Extender Kit for Hard Top Plus, Adds containment for 4 additional drums. No Drain.
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

Common questions
Warehouse Gear Hub is an authorized national distributor of material handling and safety equipment. If your answer is not here, a specialist will pick up the phone.
Who is Warehouse Gear Hub?
An authorized national distributor of industrial equipment, material handling systems and regulatory safety solutions, supplying manufacturing facilities, commercial warehouses, government entities and small businesses nationwide.
We partner directly with the brands we carry, which is how we keep facilities compliant with OSHA and EPA standards without boutique pricing. Need a formal quote, volume pricing, or to buy on a corporate PO? Submit an RFQ and our team returns a customized quote within 2 business hours. Tax-exempt organizations should contact us before ordering so we can apply your status up front.
Reach a specialist directly on 1-800-794-1049, Monday to Friday, 8:00 AM to 4:00 PM CST. Emails received in business hours are answered within two hours.
What happens after I purchase?
You get an order confirmation straight away. An equipment specialist then reviews the order and confirms freight mode before anything is dispatched, so fit and delivery are checked by a person rather than just a cart.
Most orders ship within 3 to 5 business days and tracking is emailed the moment the unit leaves. Larger equipment travels by LTL freight to curbside, and the carrier calls you to arrange a delivery window. If your site has no loading dock, add liftgate service on the product page before checkout.
Is my product authentic and does it come with warranty?
Yes. Warehouse Gear Hub is an authorized distributor and we buy direct from the brands we carry, so every unit arrives new and genuine, backed by the manufacturer's own warranty. Nothing we sell is grey-market or refurbished.
Warranty terms are set by each manufacturer and vary by model, so rather than quote a blanket figure we print the exact term on the product's own page wherever one applies. Not every item carries a stated warranty. If you need coverage confirmed in writing before you order, call us and we will get it from the manufacturer.
What happens if there is a problem with my order?
Inspect the shipment before you sign for it. Note any damage on the delivery receipt, because that receipt is what a freight claim rests on and a clean signature makes damage far harder to recover.
Then call 1-800-794-1049 or email info@warehousegearhub.com with photos from several angles, and we file the freight claim on your behalf within 48 hours. If anything arrives missing or incorrect, tell us right away and we will put it right.
Eligible items can be returned within 30 days of receipt in their original packaging. Some products carry a restocking fee of up to 15% and return shipping is usually the buyer's; we confirm both before you commit to a return, so there are no surprises.
Where will my order ship from?
Direct from the manufacturer or their nearest regional distribution center rather than from one central warehouse. That is normally the shortest and cheapest route to your dock, though it does mean the origin depends on the brand and on where you are.
If you need the origin and transit time in advance, whether for scheduling receiving or booking a delivery appointment, ask when you request your quote and we will confirm both.
Can I get a discount if I pay via wire transfer or ACH?
Yes. Paying by wire transfer or ACH takes 2% off your order total, because it saves the card processing fees. On a 30,000 dollar machine that is 600 dollars back in your budget.
Request a quote or call 1-800-794-1049 and your specialist will issue the invoice with the 2% already applied.
