SMACK DOWN Drain Seals
As the name suggests, simply smack these drain seals down on the drain to stop the spills from going down in the drain. The unique urethane construction allows SMACK DOWNs to deform and seal off most drains, temporarily sealing to any smooth surface. The reinforcing mesh is enclosed between layers of polyurethane for increased durability and resistance to tearing.

SMACK DOWNS are a valuable addition to any emergency response plan, spill kit, SPCC or stormwater management program. The non-specified top or bottom makes it a great product to slap down when time is of the essence. It resists oil, water and most aggressive chemicals. When you are done using it, simply wash it off with soap and water.
