This sealed concrete manhole ring with double-step configuration is designed for installation within underground drainage systems. Measuring 1200mm in diameter and 1 metre in height, it serves as a structural component for access chambers and inspection points in piping networks.
Suitable for use in both new and replacement manhole construction, the robust ring simplifies site assembly while helping to manage water ingress and providing safe step access for maintenance teams. Typically used in civils, drainage, and infrastructure applications requiring solid, long-lasting chamber structures.
