Clear Ultra Drain Seal made of urethane construction allows the pad to deform and seal off most drains. Fits the majority of New Zealand stormwater drains, size 915mm x 915mm. Clear drain seal makes it easy to determine that an effective seal has been achieved. Reinforced mesh is "sandwiched" between layers of polyurethane - increases durability and resistance to tearing. Unique, urethane construction allows the pad to deform and seal off most drains - temporarily "seals" to any smooth surface. A valuable addition to any emergency response plan, spill kit or stormwater management program. Unlike some alternative products, BOTH sides will quickly seal drains - there is no specified "top" or "bottom". Flexible, non-absorbing material with reinforced, tear-resistant mesh. Resists oil, water and most aggressive chemicals, cleans with soap and water. Dimensions: 915mm (L) x 915mm (W) x 10mm (H). Weight: 9kg
