450 x 450 recessed manhole covers

450mm square is one of the more common sizes in domestic settings. A 450 x 450 manhole cover will usually be found in the driveway or garden in domestic premises but can also been seen in commercial settings. On our website we list clear opening sizes in millimetres - the dimensions for this cover size are 450mm x 450mm (or 17.72" x 17.72").

 

How do I know a 450 x 450mm cover is the correct size?

The manhole cover size you require is determined by the clear opening size, which is referring to the size of the chamber opening. Measurements will need to be taken from the inside walls of the chamber opening, from one side to the other. When you lift your existing cover, if you find your opening / chamber is 380-480mm you are likely to need a 450mm cover.

If your cover size is closer to 300mm or 600mm you may need to consider a smaller or larger cover. We're here to help if you face any difficulty or have additional questions.

 

Spotlight: 450SR Grass Manhole Cover

Our exclusive GrassTop range are manhole covers designed to be infilled with grass (or artificial grass). These covers replace an ugly solid top drain lid in the garden and make the area look seamless, while still providing you with access to the drain below via the integrated lifting points in the cover.

Where aesthetics are important, this is the ideal solution for a perfect looking lawn. By default these covers are pedestrian loading but as a special order they can be made to any traffic loading needed.
