Ultra-Spill Decks provide the lowest profile spill containment units available. The modular spill decks are available in 1, 2 and 4 drum models and can be used alone for smaller containers or connected via bulkhead fitting to make a custom spill containment area for just about any application. The bladder systems utilize a bladder that unfurls in the case of a catastrophic spill allowing the entire drums contents to be captured.
