U172127 / 2127 DRAINSEAL ULTRA 24"X24"X3/8" UItraTech Ultra-DrainSeals® Patent pending Ultra-DrainSeals® are a valuable addition to any emergency response plan, spill kit or stormwater management program. Completely reversible, both sides of 3/8" thick non-absorbing pad deform to temporarily seal to any smooth surface and stop most drains. A reinforcing mesh is sandwiched between the two polyurethane layers for increased durability and resistance to tearing. Resists oil, water and most aggressive chemicals. Clean with soap and water. Optional wall mount units allow quick response to any spill. Mounting hardware included. Order DrainSeal® separately.
