Low profile, "in line" designs save valuable floor space and comply with spill containment regulations. 55 gal drums are big and bulky. That's why they often get lined up along a factory or warehouse wallto keep them out of the way until they are needed. So it only makes sense to create spill containment that can accommodate that sort of set up. The Ultra-Inline Spill Decks do just that. Using 2-drum Ultra-Spill Decks and connecting them with bulkhead fittings and bladder attachments, we can provide spill containment that "hugs the walls" and stays out of the way. And because of the connection of multiple decks and the additional containment capacity of the 66-gal bladders, all of the systems meet the EPA and SPCC spill containment regulations.
