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.

Inspection Chamber Sets

Our chamber sets represent the most popular configurations of bases, risers and manhole covers based on our experience of selling these products over a great many years. We only source these chamber components from market leading suppliers in this field such as ClarkDrain, FloPlast and Marley.

Inspection chamber sets are ideal for those customers who have a good idea of the finished height of the chamber required and the type of manhole cover that will be needed. Final alterations can still be made on site by trimming the risers if required.

On new build sites and extensions, inspection chamber details are usually shown on the plans, making the purchasing of chambers sets a relatively straightforward proposition. As we also sell all of the components individually is it still easy to make amendments (for example adding additional risers) should the chamber specification need to be changed during the build process.

Inspection chambers are a vital part of the underground drainage system, whether it be residential or commercial. They are necessary to provide access into various key points of the underground drainage system. Such access points are used for maintenance tasks such as inspecting and testing pipes to ensure that effluent is flowing correctly and to clear any potential blockages with drain rods or high pressure jetting as required.
