The Manhole cover is a plate that is temporarily adapted to a manhole. It effectively protects the fall of distracted passers-by or operators who might fall into the open gaze.
The Manhole cover is made of an HD polymer plate that has properties that are resistant to load, future-proof, and many chemical components.
The Manhole cover is positioned on the lip of the manhole.
With its ventilation holes with a diameter of 40 mm, the Manhole cover ensures perfect air circulation for ventilation manoeuvres in the network, even when it is closed. Its installation is simple and quick (in a few seconds).
The Manhole cover is available in standard sizes of Ø 630 mm and Ø 825mm. It can exist in other dimensions (see Tractel).
In all cases, the operator must check that the Manhole cover is compatible with the manhole on which it is going to be installed.
