This concrete top section is intended for use with inspection chamber covers and frames in drainage installations, measuring 600 x 450 x 110mm and weighing 46kg. It serves as the final element at the chamber opening, providing a stable base to support covers and distribute surface loads effectively.
On site, the section is commonly installed at ground level in domestic drainage systems to align with the finished surface. It helps ensure a proper fit for frames and covers, making maintenance access straightforward and assisting in limiting water or debris from entering the chamber.
