320mm Inspection Chambers and Covers

Our range of 320mm inspection chambers are manufactured with quality materials and engineered to last. Chambers are made up of segmented sections, known as risers, to enable installers to construct a chamber to their desired invert height quickly and easily.

Our 320mm inspection chamber bases come in two configurations, a) a 3-inlet base with 2 x 45° 110mm inlets and b) a 5-inlet base with 2 x 45° inlets & 2 x 90° inlets.

The chamber risers are 135mm deep and can be stacked to achieve your desired invert.  Invert level should not exceed 600mm.

We also offer a range of manhole covers to suit the 320mm inspection chamber
