Inspection Chamber Complete Set With 46mm Deep Block Paviour Cover - 450mm Diameter
This chamber set includes all of the components required to form a 450mm diameter inspection chamber with a 46mm 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 in a patio area or paved application.
The overall depth of the chamber from the invert level to the top of the manhole cover is 822mm. 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. Alternatively if you need to increase the height of the chamber you can add more D916 risers up to a height of 1200mm with the standard cover and frame (or up to 3m if you use a CLKS499 access restrictor).
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 5 Tonneload rating making it suitable for use in domestic driveways. It comes with lifting keys.
