600 x 450 Manhole Covers

600 x 450 manhole covers are one of the most commonly specified rectangular access cover sizes in the UK. Suitable for both replacement and new installations, they’re available in a range of load classes to suit domestic, commercial and highway applications.

Whether you’re replacing an existing cover or specifying one for a new project, selecting the correct load class is just as important as choosing the correct size.

Choosing the Right Load Class

600 x 450 manhole covers are available in multiple load classes depending on where they’re being installed.

  • A15 – Pedestrian only
  • B125 – Domestic driveways and light vehicle areas
  • C250 – Car parks and light commercial developments

Always ensure you match both the clear opening and the required load class before ordering.
