Expand Your Drum Storage Capacity Without Starting Over
🔒 100% Secure Checkout
The Ultra Hard Top Extender Kit lets you add drum storage to your existing Ultra Hard Top Plus Spill Pallet — no new base unit required. This built-to-spec kit includes a spill pallet, black connecting wall, and two sets of roll tops with swing-out doors, so you scale your industrial-grade containment footprint on your terms. Available in two drain configurations to match your existing setup.
At Tank Vault, we verify compliance requirements for your state and application before the order ships. The Ultra Hard Top Extender Kit is no exception — we confirm compatibility with your existing Ultra Hard Top Plus Spill Pallet and validate that your expanded setup maintains EPA-compliant secondary containment. The industrial-grade spill pallet, black connecting wall, and two roll top door assemblies arrive as a matched set built-to-spec for seamless integration. No guessing whether the extender fits your base unit. No discovering after delivery that the components don't align. We catch mismatches before your order leaves, so your expanded drum storage passes inspection on the first walkthrough.
When your drum count grows, your containment has to keep pace. The Ultra Hard Top Extender Kit attaches to your current Ultra Hard Top Plus Spill Pallet using the included black connecting wall — no separate base unit required, no reconfiguring your existing layout. Two roll top assemblies with swing-out doors give your expanded section the same access and weather protection as your original setup. Available in no-drain and with-drain configurations to match your base unit's plumbing. This field-proven approach means you scale drum storage capacity on-site without pulling your operation offline or waiting for a full replacement system.
Adding drums means adding regulatory exposure. The Ultra Hard Top Extender Kit maintains the same secondary containment standard as your Ultra Hard Top Plus base unit, so your expanded configuration stays code-compliant without separate engineering review. The included spill pallet provides contained sump capacity, while the connecting wall seals the junction between old and new sections. Every Tank Vault order ships with relevant compliance documentation so your inspector sees a unified, properly specified drum storage system — not a patched-together expansion. Select the drain configuration that matches your base unit to keep your spill management plumbing consistent across the entire setup.

“We needed to add six more drums to our fleet yard but didn't want to replace our existing Hard Top Plus setup. Tank Vault walked us through the extender kit, confirmed the drain match, and it bolted right up. Inspector signed off on the expanded layout first visit.”
