This concrete top section is designed for use with a metal cover and frame, measuring 1000 x 675 x 50mm and weighing 89kg. It is typically installed as part of domestic drainage inspection chambers, providing a solid and stable seating for the cover assembly.
On site, it is commonly placed on top of manhole rings to complete the chamber, allowing secure fitting of a metal access cover. The section can be jointed using bituminous or butyl compounds, which aids in achieving a watertight finish quickly without needing a concrete surround.
