UltraTech's patented flow through bulkhead fittings not only join Ultra Spill Decks securely, they also allow liquid spills to flow from one deck to the next in order to increase the coverall containment capacity of your Ultra Spill Deck containment system.
Use 1 bulkhead fitting when joining a 1 drum Spill Deck and 2 when joining 2 and 4 drum Spill Decks.
