Elmac Technologies® range of non-sparking low pressure manhole covers provides easy access to low pressure storage tanks for maintenance and cleaning purposes. The manhole is secured by a transverse beam which is attached to the centre of the cover. This ensures even distribution of the retaining force to form a gas tight fitting.
