Other than the spill deck, you’ll need one bulkhead fitting (Product CHU1073) and one t-strip ( Product CHU1131) for every 660mm of spill deck length that is connected. For example, if you’re connecting a 4-drum spill deck to another 4-drum spill deck you would need two bulkhead fittings and two t-strips. If, on the other hand, you were connecting a 1-drum spill deck to the short end of a 2-drum spill deck, you would only need one each of the bulkhead fitting and t-strip. 

Because of the difference in height, the Ultra-Spill Deck Plus modules can only be attached to other Ultra-Spill Deck Plus modules and are not compatible with the standard (146mm height) spill decks.

Yes. All that is required is a 39mm hole saw (31mm will also work). On each side of the Ultra-Spill Decks are “dimpled” areas that indicate where holes are to be drilled. Center the hole saw in the area you need to be drilled and carefully cut the hole(s) for your bulkhead fittings. File or “flame” any rough or sharp edges prior to connecting.

Sidewall plugs (Product CHU2221) can be used if you are no longer connecting a spill deck and therefore have a hole that needs to be plugged.

Yes, all grating surfaces on the spill decks are slip-resistant.


The t-strips lay across the point where two spill decks come together. By “bridging the gap” this piece diverts spills to either of the decks and keeps any spillage from getting between the units.

One bulkhead fitting and one t-strip for each 685mm of spill deck that is being connected.


(Note: The answer to this question is based on one assumption: That the spill decks are being used with 205L drums). By themselves, the 1-drum, 2-drum and 4-drum spill decks do not meet EPA requirements. They must be connected to a bladder or another Ultra-Spill Deck to increase the total sump capacity to 205 litres minimum.
