Sealing mat, mat thickness 8 mm, reusable, round, 450 mm. Supplied = assembled. Mat height = 8 mm. Diameter = 450 mm. Material = polyurethane. Model = universal. Situation = reaction to leaks (emergency) , leak prevention. Property = diverting/containing/collecting. Type of leakage = spilling, drip leaks, surface leaks. Application = normal. Frequency of use = multiple. Place of use = indoor and outdoor use. Product type = flexible seals. Protection from escaping hazardous substances - temporarily seals manholes, drains etc. quickly. Resistant against many chemicals, oils and water based liquids. Robust, reusable - simply clean with soapy water. Special plastic bonds perfectly to the surface, flexible and leakproof. Temporary barrier for emergencies and as a preventative measure. Sealing mats for quick, temporary sealing of drains, gullies etc. Mat thickness or mat height 8 mm. The Drainprotectors (sewer covers, gully covers) made of polyurethane, available in various sizes, prevent leaking liquids from entering drains, grates or manhole covers and therefore protect sewer systems from contamination. The sealing mat only has to be placed over the drain and the leakage is stopped. Drainprotector sealing mats are resistant to most oils as well as a variety of water-based industrial chemicals. Due to their flexibility, they can be used immediately on almost any surface, are reusable (easy to clean with soap and water) and therefore extremely economical. Please note: the sealing mats cannot be driven on and are not electrically conductive. The mat should overlap with the opening by approx. 80 mm on all sides.
