Plasti-Fab Durable Fiberglass Mag Metering Manholes
The Plasti-Fab composite Mag Meter Manhole was durably designed for frequent and convenient use. The one-piece, monolithic construction prevents leaky joints and a full opening hinged lid and bright white gel coating offers better interior light conditions. These features create a cleaner, safer environment for servicing.
Not only are fiberglass Mag Meter Manholes appropriate for large sized flumes, but they are an advantage when installing small flumes as well. Standard 4’ concrete manholes cannot always accomodate small flumes without additional installation and grout work. The PMM has factory formed inlet and outlet transition approach sections assuring proper conditioning.
