Once installed the cover lid causes minimal disturbance for a passing vehicle. The liquid tight floor cover is applied at gasstations, factories, garages, carwashes, chemical plants, etc.
The heavy model has a 4 mm thick stainless steel lid. This cover has a load taking capacity of 1750 kg according to NEN/EN 124 and is normally used outside, to seal holes in normal to heavy loaded liquid tight floors.
