Manhole covers

The manhole covers we offer are ADR-compliant and fulfil the European standards EN13317 and EN13314. We stock standard versions but can also deliver special configurations if required.

Flexible hole configuration
The 24-bolt version with a spring-loaded inspection cover (opens at 300mbar) is the base for most other versions and it is mainly the hole configurations for the equipment that differ from market to market. Some require pressure/vacuum valves with connection to vapour recovery, some optical or thermistor sensors, others emergency evacuation valves and so on. Should the configuration required not be shown, please contact us.
