Product Details
Cast Iron Manhole Cover and Frame 600L x 600W x 44H - B125 Class
Manhole covers are made of cast iron. These covers need to be heavy
so that when vehicles drive over them, they do not become
dislodged. Manhole covers normally weigh 100+ pounds each.
Some have open pick holes which allow water to enter the manhole.
Others have concealed pick holes which do not go all the way
through the cover or lift handles such as drop handles or ring
handles.
Manhole covers can be bolted to the frame for security reasons.
Manhole covers can also have a gasket on the bottom of the cover
and bolted to the frame which is normally considered watertight.

Features : Inverted vee seatings combine with three point suspension to

Functions : Designated to be used in Government roadway drainage projects
and maintenance projects.
Applications : For Storm Water (with circumscribed raised stubs on the cover)
For Foul Water (with rectangular raised stubs on the cover)
