Warning Cover / Warning Cover

Warning Cover

Warning Cover is a manhole cover with a cone on the reverse side. Its cone can provide a clear signal when workers are doing down hole operation. This enhances road safety as it helps to draw drivers and walkers’ attention. Different kinds of covers can be seen everywhere in the city streets, such as sewage discharge covers, electric power covers. Workers need to open the covers regularly to inspect or maintain the down hole facilities. To ensure their smooth work and people’s safety, a cone needs to be placed next to the wellhead. Warning Cover combines the function of a cover with a cone, there’s no need for workers to bring a cone anymore.
