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) 3-inlet base with 2 x 45° 110mm inlets
  • b) 5-inlet base with 2 x 45° 110mm inlets & 2 x 90° 110mm inlets

The chamber risers are 135mm deep and can be stacked to achieve your desired invert. Invert level should not exceed 600mm and we offer level invert inspection chambers to help you maintain precise measurements.

An inspection chamber is an underground enclosure in plumbing and drainage systems used for maintenance, inspection, and access points. It often features a removable cover, known as a manhole cover, which provides entry to the chamber. These covers come in various materials and sizes, ensuring easy and secure access.
