What size manhole cover do I need?
Common domestic manhole covers are 450 by 450mm, 600 by 450mm and 600 by 600mm as clear opening sizes. The right load rating matters too, from light foot traffic up to driveway and road use.
Manhole and inspection covers are sized by their clear opening. Typical domestic sizes are 450 by 450mm, 600 by 450mm and 600 by 600mm, with the size chosen to match the chamber below.
Just as important is the load rating. Lighter covers suit pedestrian areas, while covers in a driveway need a higher rating to take vehicle loads. Recessed block paving covers let you continue the finish across the cover.
