FP McCann’s bespoke DN1500 and DN1800 Easi-Base™ units complement our existing manhole ranges and are produced as monolithic units, utilising standard manhole tongue and groove joints for connection with standard manhole chambers.
The units are produced wholly from concrete and provide a variety of connection orientations using the Predl Clock System. They can accommodate concrete, clay, twinwall, ductile iron and uPVC pipes.
The table below gives the dimensions associated with each size, including the overall height of the unit, the invert level for each different pipe diameter and the combination of pipe diameters accommodated. All Easi-Base™ units are made level to soffit (i.e. level-benching).
All sizes are in mm | * 2 part unit / max Δ per unit | † 1 unit ex Knockloughrim depot
