Product Details

Concrete reducing slabs are used in the main shaft construction of manhole chambers to suit up to and including 4000mm chamber sections. They are generally manufactured with a 900mm, 1050mm or 1200mm circular reducing section and are used to reduce the access point opening size into the chamber section

Benefits of the system include:

  • 900mm, 1050mm or 1200mm reducing section.
  • Eccentric access positioning.
  • Fits flush to the chamber ring.
