How do I measure my manhole cover?
All manhole or access covers are measured by their aperture size/ hole size so you will have to lift your existing cover or measure the hole you want to cover first.
If you already have a cover its good practise to measure the overall size of the cover with frame so that you know any new cover will also work well for your space.
Then be sure to check the depth you have to work with too, both for the internal tray depth you need for your flooring but also with the height/ hole depth you have to cover.
