Top sections

Top sections for 750mm x 600mm and larger chambers act as reducing slabs, enabling standard 600mm x 450mm covers to be fitted irrespective of the size of chambers involved.

To provide concrete top section for 1000mm x 675mm requires:

  • Top section for metal cover and frame 1000mm x 675mm (i.e. reducer).
  • Top section for concrete cover 600mm x 450mm and concrete cover slab.

Concrete cover slabs

Concrete cover slabs are supplied to suit the top sections, and are 695mm x 540mm overall, 60mm thick and weigh 55kg.
