This chamber set includes all of the components required to form a 450mm diameter inspection chamber with an 80mm deep recessed cover - one base section, two 235mm sectional risers and a 580mm square recessed cover and frame (450mm clear opening).
This chamber is ideal for use with 65mm block paving or slabs.
The overall depth of the chamber from the invert level to the top of the manhole cover is 856mm. If you need to make small adjustments to the height then the sectional risers may be cut to size using a standard fine-toothed saw.
The main channel of the base is left open and the side inlets are blanked off with integral blanking plugs - simply remove the blanking plug by pushing it out from within the base to open and use the side inlets.
The cover has a 10 Tonneload rating. It comes with lifting keys.
